        MARTHA CRAIG DAUGHTREY, Circuit Judge. Neil A. Morgan II and Anita L. Graf
sued Fairfield County, Ohio, three of its officials, and five members of its sheriff’s department
under 42 U.S.C. § 1983, claiming Fourth Amendment violations. Specifically, Morgan and Graf
alleged that individual officers of the county’s SCRAP unit—Street Crime Reduction and
Apprehension Program—violated their Fourth Amendment rights when they surrounded
Morgan’s and Graf’s house, without a warrant or exigent circumstances, in order to perform a
‘knock and talk.’1 They also claimed that the county violated their Fourth Amendment rights by
making such illegal entries of property a policy or practice. The district court granted the
defendants’ motion for summary judgment in full. The district court was correct to conclude that
the law was not clearly established, so that the claims against the individual officers failed on
qualified immunity grounds. The district court was wrong, however, to conclude that the county
was not liable for injuries caused by a policy that directed officers to make warrantless entries
onto constitutionally protected property with no regard for—or even recognition of—
constitutional limits. For these reasons, we affirm in part and reverse in part.

                                               BACKGROUND

        Morgan and Graf owned a home together on about a one-acre lot. The front of the house
faced the road, and a sidewalk ran from the road to their front door. In the front window and on
a vehicle parked on the property were no-trespassing signs. There were neighboring homes—
each approximately 300 feet away. At the time of the events of this case, one of the neighboring
houses was occupied; the other was empty. There were only limited sightlines between the
houses and no residences across the street or behind Morgan’s and Graf’s house.

        In the back of the house there was a second-story balcony that was not visible from the
front of the residence. There were no stairs to the balcony, so that the only way to access it was

        1A  ‘knock and talk’ is an investigative technique in which police, without a warrant, knock on a suspect’s
door and ask to speak with the suspect or for consent to search. See United States v. Thomas, 430 F.3d 274, 277 (6th
Cir. 2005).
 No. 17-4027                             Morgan v. Fairfield Cty., Ohio                                    Page 3


through the house. On one side of the balcony was a privacy fence, blocking the view to the one
neighbor’s house that was occupied. On the other side, large trees blocked the view to the
unoccupied neighboring house.

         The county’s SCRAP unit received two anonymous tips that Morgan and Graf were
growing marijuana and cooking methamphetamine at their house. The SCRAP unit was familiar
with Morgan and Graf; they had conducted a ‘knock and talk’ a year earlier and let Morgan and
Graf off with a warning. The two new tips were not sufficient to establish probable cause for a
warrant, however, and so the SCRAP unit decided to do another ‘knock and talk.’

         Five members of the SCRAP unit went to the house and, following their standard
practice, surrounded the house before knocking on the door. One officer was stationed at each
corner of the house, and one approached the front door. The officers around the perimeter were
standing approximately five-to-seven feet from the house itself.                     The officers forming the
perimeter could see through a window into the house on at least one side of the building.

         With the officers in position, the officer at the front door—Deputy Lyle Campbell—
knocked and spoke briefly with Graf. Graf shut the door, remaining inside.2 While Campbell
was speaking with Graf, one of the officers positioned in the back of the house noticed seven
marijuana plants growing on the second-floor back balcony and notified the other members of
the SCRAP unit. By the time Campbell learned of the plants, Graf already had closed the front
door. Fearing destruction of evidence, Campbell then demanded that Graf return and open the
door. Almost immediately after voicing that demand, he opened the door, entered the house, and
brought Morgan and Graf outside to wait for a search warrant.

         An Ohio court issued a search warrant based on the officers’ observation of the marijuana
plants. During the ensuing search, the police found weapons, drugs, and drug paraphernalia.
Morgan and Graf were arrested and charged in state court. The trial court denied Morgan’s and
Graf’s suppression motion, after which Morgan pleaded guilty and Graf was found guilty by a

         2Although  the parties dispute why Graf closed the door, no one disputes that she did. Graf insists that
Campbell put his foot across the threshold and she told him that if he did not have a warrant he would have to leave.
Campbell, on the other hand, stated that Graf closed the door so that she could lock up her dog. The factual
discrepancies are immaterial—the case is about the officers around the perimeter, not the officer at the front door.

jury.   On appeal, however, the denial of the suppression motion was overturned and the
convictions vacated. The State of Ohio subsequently dropped the charges.

The proceedings below

        After the dismissal of the charges, Morgan and Graf filed this 42 U.S.C. § 1983 action,
alleging violations of their Fourth and Fourteenth Amendment rights to be free from
unreasonable searches and seizures. They sued four members of the SCRAP unit in both their
individual and official capacities, and they sued two Fairfield County commissioners and the
Fairfield County sheriff in their official capacities. They also sued the county itself.

        Morgan and Graf alleged that forming a perimeter around the house intruded on their
curtilage, an area protected by the Fourth Amendment. What is more, the intrusion was not a
one-time event—it was the county’s policy to do so during every ‘knock and talk.’ On cross-
motions for summary judgment, the district court dismissed all of the claims.

        First, addressing the claims against the officers in their individual capacities, the district
court concluded that the officers were entitled to qualified immunity. Specifically, the court
held, qualified immunity was appropriate because even if intruding onto the curtilage violated
the Fourth Amendment, it was not clearly established that such an action was a violation at the
time of the ‘knock and talk’—June 19, 2012. The district court relied on the unpublished
decision in Turk v. Comerford, 488 F. App’x 933 (6th Cir. 2012), which this court had issued a
month after the ‘knock and talk’ incident at issue here. In Turk, police had surrounded a home
for a ‘knock and talk’ because they believed that a dangerous fugitive was inside. Id. at 935.
The Turk panel looked to the opinion in Hardesty v. Hamburg Township, 461 F.3d 646 (6th Cir.
2006), which recognized that curtilage gets Fourth Amendment protection but concluded that
officers may intrude on curtilage to look for someone during a ‘knock and talk’ if they have
indications that someone is inside and just not answering the door. Because it was unclear
whether the logic of Hardesty applied to surrounding a house “with no warrant, exigent
circumstances, or consent,” the panel in Turk concluded that the police were entitled to qualified
immunity. 488 F. App’x at 947–48. Relying on Turk, the district court here concluded that if the
 No. 17-4027                              Morgan v. Fairfield Cty., Ohio                                    Page 5


law was not settled in July 2012, it was not settled in June 2012. Thus, the district court
reasoned, the officers were entitled to qualified immunity.

         Next, the district court addressed the official-capacity claims and the claim against the
county—correctly analyzed as one claim against Fairfield County—and concluded that Morgan
and Graf could not meet the standard for municipal liability required by Monell v. Department of
Social Services, 436 U.S. 658 (1978). The court noted that Morgan and Graf could not show that
the policy was facially unconstitutional because there could be instances in which the policy
would be applied constitutionally. Nor, said the district court, could they satisfy the burden of
showing that the county was deliberately indifferent to unconstitutional application of its policy.
The district court thus granted summary judgment in favor of all of the defendants on all claims.

                                                 DISCUSSION

Standard of review

         This court reviews a grant of summary judgment de novo. Daughenbaugh v. City of
Tiffin, 150 F.3d 594, 597 (6th Cir. 1998). “In the qualified immunity context, ‘this usually
means adopting . . . the plaintiff’s version of the facts,’ unless the plaintiff’s version is ‘blatantly
contradicted by the record, so that no reasonable jury could believe it.’” Stoudemire v. Mich.
Dep’t of Corr., 705 F.3d 560, 565 (6th Cir. 2013) (alteration in original) (quoting Scott v. Harris,
550 U.S. 372, 378, 380 (2007)). Summary judgment is appropriate only if there is no genuine
dispute of material fact. Anderson v. Liberty Lobby, Inc., 477 U.S. 242, 247–48 (1986). A fact
is material if its resolution will affect the outcome of the lawsuit. Id. at 248.3

Qualified immunity

         Government officials sued in their individual capacities for constitutional violations are
free from liability for civil damages unless (1) they violate a constitutional right that (2) was
clearly established at the time that it was violated. See Harlow v. Fitzgerald, 457 U.S. 800, 818


         3The  county asserts facts in its brief that are not discussed in this opinion because they are immaterial or
unsupported in the record. For example, the county outlines overall amounts of various drugs that the SCRAP unit
confiscated in 2012; explains how the unit prepared for knock and talks; and even asserts that if the knock-and-talk
policy is unconstitutional, the SCRAP unit will have to disband entirely.
 No. 17-4027                        Morgan v. Fairfield Cty., Ohio                           Page 6


(1982). Courts can address these two elements in any order. Pearson v. Callahan, 555 U.S. 223,
236–37 (2009). And although this decision turns on the second element—whether the law was
clearly established—we have the ability, if not the responsibility, to clarify the state of the law in
this circuit so that government agents can understand the limits of their power and that citizens
will be protected when those limits are transgressed. For that reason, we address both parts of
the qualified-immunity analysis.

Fourth Amendment violation

       “It is well settled” under the Fourth Amendment that a warrantless search is “‘per se
unreasonable . . . subject only to a few specifically established and well-delineated exceptions.’”
Schneckloth v. Bustamonte, 412 U.S. 218, 219 (1973) (alteration in original) (quoting Katz v.
United States, 389 U.S. 347, 357 (1967)). That raises two questions: did the SCRAP unit search
Morgan’s and Graf’s property and, if so, did that search fall under one of the exceptions to the
warrant requirement?

       The answer to the first question is yes, the SCRAP unit searched the property for Fourth
Amendment purposes. When the government gains information by physically intruding into
one’s home, “‘a search within the original meaning of the Fourth Amendment’ has ‘undoubtedly
occurred.’” Florida v. Jardines, 569 U.S. 1, 5 (2013) (quoting United States v. Jones, 565 U.S.
400, 406 n.3 (2012)). But it is not just the physical house that receives the Amendment’s
protection. The curtilage—the area “immediately surrounding and associated with the home”—
is treated as “part of [the] home itself for Fourth Amendment purposes.” Oliver v. United States,
466 U.S. 170, 180 (1984). That is because “‘[t]he protection afforded the curtilage is essentially
a protection of families and personal privacy in an area intimately linked to the home, both
physically and psychologically, where privacy expectations are most heightened.’” Collins v.
Virginia, 138 S. Ct. 1663, 1670 (2018) (quoting California v. Ciraolo, 476 U.S. 207, 212–13
(1986)).

       Whether a part of one’s property is curtilage generally involves a fact-intensive analysis
that considers (1) the proximity of the area to the home, (2) whether the area is within an
enclosure around the home, (3) how that the area is used, and (4) what the owner has done to
 No. 17-4027                        Morgan v. Fairfield Cty., Ohio                           Page 7


protect the area from observation by passersby. United States v. Dunn, 480 U.S. 294, 301
(1987). But these factors are not to be applied mechanically: they are “useful analytical tools
only to the degree that, in any given case, they bear upon the centrally relevant consideration—
whether the area in question is so intimately tied to the home itself that it should be placed under
the home’s ‘umbrella’ of Fourth Amendment protection.”             Id. at 301.    Often that central
consideration requires little more than a commonsense analysis because the concept is “familiar
enough that it is ‘easily understood from our daily experience.’” Jardines, 569 U.S. at 7 (quoting
Oliver, 466 U.S. at 182 n.12).

       Under that commonsense approach, the area five-to-seven feet from Morgan’s and Graf’s
home was within the home’s curtilage. Even when the borders are not clearly marked, it is
“easily understood from our daily experience” that an arm’s-length from one’s house is a “classic
exemplar of an area adjacent to the home and ‘to which the activity of home life extends.’” Id.
(quoting Oliver, 466 U.S. at 182 n.12). The right to be free of unwarranted search and seizure
“would be of little practical value if the State’s agents could stand in a . . . side garden and trawl
for evidence with impunity.” Id. at 6. And the right to privacy of the home at the very core of
the Fourth Amendment “would be significantly diminished” if the police—unable to enter the
house—could walk around the house and observe one’s most intimate and private moments
through the windows. Id.

       But not only were the SCRAP unit members positioned on the sides of the house, they
were in the backyard, too. Indeed the backyard is where they discovered the marijuana plants,
the cause of the injuries alleged by Morgan and Graf.             And “the law seems relatively
unambiguous that a backyard abutting the home constitutes curtilage and receives constitutional
protection.” Daughenbaugh, 150 F.3d at 603; see also United States v. Jenkins, 124 F.3d 768,
773 (6th Cir. 1997). That is true especially when, as here, there are no neighbors behind the
house and the backyard is not visible from the road.

       The county mistakenly focuses its application of the Dunn analysis on the backyard
balcony itself, arguing that the there is no search because the balcony was not part of the
curtilage. But even if the county were correct that a backyard, second-story balcony with no
outside access was not part of the curtilage, it would make no difference here, because the
 No. 17-4027                        Morgan v. Fairfield Cty., Ohio                           Page 8


balcony is not what is at issue. The curtilage that the officers are said to have entered is the area
surrounding the house, five-to-seven feet from the residence. Regarding that area, the county
argues only two points—first that the immediate perimeter surrounding the house was not part of
the curtilage because there was no fence enclosing the rear or perimeter of the house and, second,
that area was not part of the curtilage because Morgan and Graf had neighbors. Those arguments
are belied, however, by Dunn and Jardines and the “relatively unambiguous” conclusion this
court came to 20 years ago in Daughenbaugh.

       Because the area surrounding Morgan’s and Graf’s house was curtilage, and curtilage is
treated as part of the home for Fourth Amendment purposes, the officers’ entry onto the curtilage
could be justified only by a warrant or one of the recognized exceptions to the warrant
requirement. It is undisputed that the SCRAP unit had no warrant. As for exceptions to the
warrant requirement, the county argues that the entry was justified for three reasons. None,
however, is convincing.

       First, the county argues that forming a perimeter was not unconstitutional because the
officers were protecting their own safety. To be sure, officer safety can be an exigency justifying
warrantless entry.     But “[q]ualification for this exception is not easy” and requires a
particularized showing of a risk of immediate harm. United States v. Purcell, 526 F.3d 953, 960
(6th Cir. 2008). The only particularized facts that the county offers here are a contested fact, i.e.,
that Morgan was in a motorcycle gang, and a fact with no citation to the record, i.e., that Morgan
may have had a weapon. Without more, the county cannot show “the need for prompt action by
government personnel” required to conclude that delay to obtain a warrant “would be
unacceptable under the circumstances.” Id. (quoting United States v. Rohrig, 98 F.3d 1506, 1517
(6th Cir. 1996)).

       Instead of showing a particular and immediate risk, the county argues that concern for
officer safety generally allows police to enter the curtilage and form a perimeter. Yet rather than
citing a case supporting that position, the county argues that drugs and guns often go together.
Maybe. But that is no more than a general statement of correlation; and generic possibilities of
danger cannot overcome the required particularized showing of a risk of immediate harm. See
id. at 961. But, even if the officers knew that Morgan had a weapon, “[t]he mere presence of
 No. 17-4027                         Morgan v. Fairfield Cty., Ohio                         Page 9


firearms does not create exigent circumstances.” United States v. Johnson, 22 F.3d 674, 680 (6th
Cir. 1994).

       What is more, the county’s position would create an exception that would swallow the
rule. It might be safer for the police to enter the curtilage to form a perimeter; it would certainly
be easier to stop someone who might flee by establishing some sort of barrier to that flight.
Indeed, many (if not most) Fourth Amendment violations would benefit the police in some way:
It could be safer for police without a warrant to kick in the door in the middle of the night rather
than ring the doorbell during the day, and peering through everyone’s windows might be a more
effective way to find out who is cooking methamphetamine (or engaging in any illegal behavior,
for that matter).    But the Bill of Rights exists to protect people from the power of the
government, not to aid the government. Adopting defendants’ position would turn that principle
on its head.

       Next, the county argues that the officers’ presence in the backyard was not a search
because they were not there for the purpose of executing a search. Jardines forecloses that
argument. The subjective intent of officers is irrelevant if a search is otherwise objectively
reasonable, but subjective intent cannot make reasonable an otherwise unreasonable intrusion
onto a constitutionally protected area. See Jardines, 569 U.S. at 10. Notably, the county does
not attempt to distinguish Jardines—in fact it fails to cite it altogether.

       Finally, the county argues that the marijuana plants were discovered in plain view. It is a
long-standing rule that police do not conduct a search under the Fourth Amendment by seeing
something that is in plain view. After all, the Fourth Amendment does not require police to
“shield their eyes when passing by a home on public thoroughfares.” Ciraolo, 476 U.S. at 213.
The plain-view exception, however, applies only when “the officer did not violate the Fourth
Amendment in arriving at the place where the evidence could be plainly viewed.” United States
v. Taylor, 248 F.3d 506, 512 (6th Cir. 2001). As explained above, the SCRAP unit discovered
the marijuana only after entering Morgan’s and Graf’s constitutionally protected curtilage. The
plain-view exception does not apply.
 No. 17-4027                       Morgan v. Fairfield Cty., Ohio                         Page 10


       The SCRAP unit was concerned about general drug activity at Morgan’s and Graf’s
house. But the Fourth Amendment prohibited them from entering the property: they had no
warrant, no exigent circumstances, and no other exception to the warrant requirement. A ‘knock
and talk’ by police was permitted “precisely because that is ‘no more than any private citizen
might do.’” Jardines, 569 U.S. at 8 (quoting Kentucky v. King, 563 U.S. 452, 469 (2011)).
Thus, the officers’ right to enter the property like any other visitor comes with the same limits of
that “traditional invitation”: “typically . . . approach the home by the front path, knock promptly,
wait briefly to be received, and then (absent invitation to linger longer) leave.” Id. Certainly,
“[a] visitor cannot traipse through the garden, meander into the backyard, or take other circuitous
detours that veer from the pathway that a visitor would customarily use.” Id. at 19 (Alito, J.,
dissenting). Neither can the police. By doing so here, the SCRAP unit violated Morgan’s and
Graf’s Fourth Amendment rights.

Clearly established law

       Whether the law in this area was clearly established at the time of defendants’ actions
presents a closer question. “A defendant cannot be said to have violated a clearly established
right unless the right’s contours were sufficiently definite that any reasonable official in the
defendant’s shoes would have understood that he was violating it.” United Pet Supply, Inc. v.
City of Chattanooga, 768 F.3d 464, 478 (6th Cir. 2014) (brackets omitted) (quoting Plumhoff v.
Rickard, 134 S. Ct. 2012, 2023 (2014)).

       In determining the contours of the right, there is a tension between defining the right at
too high a level of generality, on one hand, and too granular a level, on the other. There does not
need to be “a case directly on point, but existing precedent must have placed the . . .
constitutional question beyond debate.” Ashcroft v. al-Kidd, 563 U.S. 731, 741 (2011). “The
general proposition . . . that an unreasonable search or seizure violates the Fourth Amendment is
of little help in determining whether the violative nature of particular conduct is clearly
established.”   Id. at 742.   Nevertheless, “general statements of the law are not inherently
incapable of giving fair and clear warning, and in other instances a general constitutional rule
already identified in the decisional law may apply with obvious clarity to the specific conduct in
question, even though ‘the very action in question has [not] previously been held unlawful.’”

Creighton, 483 U.S. 635, 640 (1987)). In all, the most important question in the inquiry is
whether a reasonable government officer would have “fair warning” that the challenged conduct
was illegal. Baynes v. Cleland, 799 F.3d 600, 612–13 (6th Cir. 2015) (quoting Hope v. Pelzer,
536 U.S. 730, 741 (2002)).

       For centuries, the common law has protected the curtilage of the house. See Oliver, 466
U.S. at 180. And the Supreme Court long has held that the curtilage is “considered part of the
home itself for Fourth Amendment purposes.” Id. That means that the police can enter the
curtilage on the same terms that they can enter the rest of the home—no more, no less. See King,
563 U.S. at 469.       Under those long-settled principles, warrantless searches “are per se
unreasonable under the Fourth Amendment—subject only to a few specifically established and
well-delineated exceptions.” Katz, 389 U.S. at 357 (footnotes omitted). A reasonable officer
thus would understand that without a warrant or an exception to the warrant requirement,
entering the curtilage violates a clearly established right.

       Despite these long-settled standards, one case from this circuit, although incorrectly
decided, requires that we grant qualified immunity. That case, Turk v. Comerford, decided
within a month of the ‘knock and talk’ in this case, found that the law was not clearly settled
against a factual background that was, in every material way, the same as here. 488 F. App’x at
947–48.

       Central to Turk’s analysis was our published decision in Hardesty, in which we held that
“[if] knocking at the front door is unsuccessful in spite of indications that someone is in or
around the house, an officer may take reasonable steps to speak with the person being sought out
even where such steps require an intrusion into the curtilage.” 461 F.3d at 654. Hardesty’s
extension of the knock-and-talk doctrine was, by its terms, limited to particular circumstances.
Id. And if our case law ended there, qualified immunity here would be improper. But in Turk,
this court read Hardesty more broadly and reasoned that because some limited intrusions of the
curtilage were allowed, it was not clearly established that surrounding a house for a ‘knock and
talk’ was in the category of unacceptable intrusions. 488 F. App’x at 947–48.
 No. 17-4027                       Morgan v. Fairfield Cty., Ohio                         Page 12


       Although Hardesty and Turk are outliers, Morgan and Graf cannot overcome their burden
of showing that the law was clearly established at the time of the search in this case. In those
two cases, this court should have reaffirmed long-settled Fourth Amendment principles. Cf.
Rogers v. Pendleton, 249 F.3d 279, 289–90 (4th Cir. 2001) (denying qualified immunity and
reasoning that allowing access to curtilage based on reasonable suspicion would “eviscerate the
principle of Oliver and Dunn that the curtilage is entitled to the same level of Fourth Amendment
protection as the home itself”). But it did not. And although unpublished cases do not upset the
state of the law, in rare instances they can show that members of this court, during the same time
period, facing the exact same question, did not think the law to be clearly established. And “[i]f
judges . . . disagree on a constitutional question, it is unfair to subject police to money damages
for picking the losing side of the controversy.” Wilson v. Layne, 526 U.S. 603, 618 (1999). For
that reason we affirm the district court’s grant of qualified immunity to the officers in their
individual capacities.

       Nevertheless, in light of recent Supreme Court decisions, neither Hardesty nor Turk
remains good law. See, e.g., Ahearn v. Jackson Hosp. Corp., 351 F.3d 226, 234–35 (6th Cir.
2003). Jardines and, more recently, Collins made clear that, outside of the same implied
invitation extended to all guests, if the government wants to enter one’s curtilage it needs to
secure a warrant or to satisfy one of the exceptions to the warrant requirement. See Jardines,
569 U.S. at 7–8. Our acknowledgment that those cases are no longer good law does not affect
the qualified-immunity analysis here, which looks to the law at the time of the challenged action.
See Harlow, 457 U.S. at 818. But it does put officers on notice that principles of Jardines and
Collins—and not Hardesty or Turk—should guide their actions going forward.

Municipal liability

       The district court erred in granting summary judgment in favor of the county and county
officials, however. A municipality is a “person” under 42 U.S.C. § 1983, and so can be held
liable for constitutional injuries for which it is responsible. Monell, 436 U.S. at 690. The scope
of that responsibility does not include respondeat superior liability: a municipality is liable only
for its own wrongdoing, not the wrongdoings of its employees. Baynes, 799 F.3d at 620. The
upshot is that municipalities can be held liable for harms caused by direct actions of the
 No. 17-4027                       Morgan v. Fairfield Cty., Ohio                         Page 13


municipalities themselves, see Pembaur v. City of Cincinnati, 475 U.S. 469, 480 (1986), harms
caused by the implementation of municipal policies or customs, see Garner v. Memphis Police
Dep’t, 8 F.3d 358, 364 (6th Cir. 1993), and harms caused by employees for whom the
municipality has failed to provide adequate training, see Arrington-Bey v. City of Bedford
Heights, 858 F.3d 988, 995 (6th Cir. 2017), cert. denied, 138 S. Ct. 738 (2018).

       Each of these different approaches to liability requires a different analysis. But each
approach seeks to answer the same fundamental question: did the municipality cause the harm
or did an individual actor? When the injury is a result of an action of an employee who has not
been trained properly, we apply “rigorous requirements of culpability and causation”—holding a
municipality liable if it has been deliberately indifferent to constitutional rights. Arrington-Bey,
858 F.3d at 995 (quoting Brown, 520 U.S. at 415). On the other end of the spectrum, when an
act of the municipality itself causes the injury, “fault and causation obviously apply.” Id. at 994.
Likewise, when an injury is caused by the straightforward carrying out of a municipal policy or
custom, the determination of causation is easy. See Garner, 8 F.3d at 364–65.

       Although Garner has been the law in this circuit since 1993, we have developed an
additional strand of case law analyzing municipal liability for policies or customs. In Gregory v.
City of Louisville, 444 F.3d 725, 752 (6th Cir. 2006), we concluded that if a challenged policy is
facially constitutional, the plaintiff must show that the policy shows a deliberate indifference to
constitutional rights. Id. Thus, Gregory analyzed failure-to-train claims and challenges to
facially constitutional municipal policies under the same standard. But as we held in Garner,
and recently reaffirmed in Arrington-Bey, “[t]here are important differences between these types
of claims” and so we must analyze them differently. Arrington-Bey, 858 F. 3d at 994. That
means that we must be careful not to apply Gregory too broadly. Gregory may help to determine
municipal liability when an employee’s interpretation of a policy causes harm. But that is not
the case here. Like Garner, this case presents a straightforward challenge to the county’s policy
itself. And, as in Garner, we apply a straightforward test: Morgan and Graf must “(1) identify
the municipal policy or custom, (2) connect the policy to the municipality, and (3) show that
[their] particular injur[ies] [were] incurred due to execution of that policy.” Alkire v. Irving,
330 F.3d 802, 815 (6th Cir. 2003) (citing Garner, 8 F.3d at 364).
 No. 17-4027                       Morgan v. Fairfield Cty., Ohio                        Page 14


       Morgan and Graf have made that showing. It is uncontested that the county’s policy
required officers to enter “onto the back” of any property during every ‘knock and talk.’ And as
acknowledged by the sheriff and members of the SCRAP unit, that policy did not give any
leeway for the officers to consider the constitutional limits that they might face. The SCRAP
unit did not weigh the characteristics of properties to determine what parts of the properties were
curtilage (and thus off limits). The policy gave no weight to the core value of the Fourth
Amendment—one’s right to retreat into his or her home “and there be free from unreasonable
government intrusion.” Collins, 138 S. Ct. at 1670 (quoting Jardines, 569 U.S. at 6). Quite the
opposite: the policy commanded that the SCRAP unit ignore those limits. It was not one
employee’s interpretation of a policy that caused Morgan’s and Graf’s injuries—the policy was
carried out precisely as it was articulated. And so, because the county’s policy itself was the
cause of Morgan’s and Graf’s injury, the county should be held liable under Monell.

                                        CONCLUSION

       It is well-established that a warrantless entry of the home or the area immediately
surrounding the home is presumed unreasonable unless it meets one of a few narrow exceptions.
The SCRAP unit, following official policy, entered the constitutionally protected area around
Morgan’s and Graf’s home without a warrant and without satisfying any of the narrow
exceptions to the warrant requirement. In doing so, they violated the Fourth Amendment. But
because of the state of this circuit’s Fourth Amendment law at the time of the search, it was not
clearly established that members of the SCRAP unit could not do what they did. For that reason,
we AFFIRM the district court’s decision granting summary judgment to the individual officers
based on qualified immunity. On the other hand, because the county’s policy itself required
officers to ignore the Constitution’s rules protecting the curtilage and the home, we REVERSE
the decision of the district court granting summary judgment to the county and the county
officials in their official capacities. We REMAND the case for further proceedings consistent
with this opinion.

       JANE B. STRANCH, Circuit Judge, concurring. I join the majority opinion in full.
I write separately only to emphasize the unique circumstances that merit applying qualified
immunity in this case. As the Supreme Court recently reaffirmed, it “has long been clear that
curtilage is afforded constitutional protection,” and “officers regularly assess whether an area is
curtilage before executing a search.” Collins v. Virginia, 138 S. Ct. 1663, 1674–75 (2018)
(citing Oliver, 466 U.S. 170, 180 (1984)). Despite this fundamental principle, our jurisprudence
has evidenced some confusion related to the police action that we refer to as “‘knock and talk’
investigations.” See United States v. Darden, 508 F. App’x 387, 388 (6th Cir. 2012); Hardesty v.
Hamburg Township, 461 F.3d 646, 654 (6th Cir. 2006) (referencing the “knock and talk
investigative technique already recognized in this circuit”). A materially indistinguishable case,
Turk v. Comerford, 488 F. App’x 933 (6th Cir. 2012), demonstrates that, at the time of the search
at issue, even federal appellate judges were struggling with assessments of curtilage in the
limited context of knock-and-talk investigations. It is rare to have a contemporaneous circuit
case revealing judicial confusion on the precise question confronted by police officers. The
existence of one here supports finding the law sufficiently unsettled that the officers should
receive qualified immunity.

       This case, moreover, presents different circumstances from even Wilson v. Layne,
526 U.S. 603, 618 (1999), referenced by the majority. There, the Supreme Court acknowledged
that the “state of the law” at the time of the constitutional violation was “undeveloped” and that a
circuit split had arisen between the alleged violation and that Court’s ultimate decision. Id. The
Supreme Court therefore declined to punish the officers’ lack of prescience. Id. But the case
before us is quite unlike the open question in Wilson, which had percolated up through the
circuits on its way to final resolution by the Supreme Court. As explained in the majority
opinion, Turk and Hardesty instead stand alone on a doctrinal spur. For purposes of this case,
however, Turk is sufficient to show that the law surrounding knock and talk investigations was

muddy at the relevant time. Though this is the unusual case in which an outlier may insulate
officers from liability, today’s decision forecloses that possibility for future cases.

             __________________________________________________________

       THAPAR, Circuit Judge, concurring in part and dissenting in part.             The Fourth
Amendment provides, in relevant part, that “[t]he right of the people to be secure in their
persons, houses, papers, and effects, against unreasonable searches and seizures, shall not be
violated.”   U.S. Const. amend. IV.     This mandate, though seemingly straightforward, has
generated a morass of legal precedent that is often confusing, contradictory, and incomplete.
After over two-hundred years, we are still not sure whether the Amendment protects privacy or
property, and, in turn, what questions are relevant for determining whether a search occurred or
if it was reasonable.

       At times like this, courts should turn back to first principles. The Amendment’s text tells
us that a Fourth Amendment violation occurs when three things are true: (1) the government
engages in a search, (2) of a person, house, paper, or effect, (3) that unreasonably violates a
person’s right to be secure in that object. To understand the meaning of those terms and place
those inquiries in context, we look to the Fourth Amendment’s meaning at the founding. For
example, history shows that a “search” meant then what it means now:               a purposeful,
investigative act (and nothing more). When we apply this meaning to Morgan and Graf’s case,
no Fourth Amendment violation occurred here: the county’s policy did not direct the officers to
conduct a search. And, for slightly different reasons, existing Supreme Court precedent compels
the same conclusion. Therefore, I concur in the majority’s decision to affirm the grant of
qualified immunity but dissent from the Monell liability holding.

                                                I.

       Some words in the Constitution are “terms of art.” See, e.g., McDonald v. City of
Chicago, 561 U.S. 742, 813–15 (2010) (Thomas, J., concurring in part and concurring in the
judgment) (“due process of law”); Collins v. Youngblood, 497 U.S. 37, 41 (1990) (“ex post facto
law”); Holland v. Illinois, 493 U.S. 474, 493 (1990) (“jury”). The word “search,” however, is
not one of them. See Carpenter v. United States, 138 S. Ct. 2206, 2238 (2018) (Thomas, J.,
 No. 17-4027                            Morgan v. Fairfield Cty., Ohio                                Page 18


dissenting); Orin S. Kerr, The Curious History of Fourth Amendment Searches, 2012 Sup. Ct.
Rev. 67, 71–72 (2012) (noting that the question of what “search” meant “rarely arose” at the time
of the founding). Instead, we look to the ordinary meaning to define the term. And the ordinary
meaning of “search” has remained unchanged since the people ratified the Fourth Amendment
over two hundred years ago. To search is “to look into or over carefully or thoroughly in an
effort to find something.”         Webster’s Third New International Dictionary of the English
Language (2002); see also 2 Noah Webster, An American Dictionary of the English Language
66 (1828) (reprint 6th ed. 1989) (“To look over or through for the purpose of finding something;
to explore; to examine by inspection; as, to search the house for a book; to search the wood for a
thief.”).1     In other words, officers conduct a search when they engage in a purposeful,
investigative act.

        Some examples bring the definition to life. Kerr, supra, at 72 (“The little evidence of
what searches meant in the late eighteenth century is mostly by way of example.”). Start with
the oppressive English search practices that inspired the founding generation to adopt the Fourth
Amendment. See Riley v. California, 134 S. Ct. 2473, 2494 (2014); Leonard Levy, Origins of
the Bill of Rights 160–61 (1992). In the mid-eighteenth century, Parliament authorized writs of
assistance, which allowed colonial customs officials to search people’s homes for goods that
were illegally imported. See Emily Hickman, Colonial Writs of Assistance, 5 New Eng. Quart.
83, 83–84 (1932); Levy, supra, at 156–57; see also Stanford v. Texas, 379 U.S. 476, 481 (1965)
(“The hated writs of assistance had given custom officials blanket authority to search where they
pleased for goods imported in violation of the British tax laws.”). These searches were intrusive.
Indeed, Charles Paxton, a famous “Surveyor and Searcher” in Massachusetts, was permitted to
enter into any ship, vessel, shop, house, warehouse, or other place “to make diligent search into
any trunk[,] chest[,] pack[,] case[,] truss[,] or any other parcel or package whatsoever.” Josiah
Quincy, Jr., Reports of Cases Argued and Adjudged in the Superior Court of Judicature of the
Province of Massachusetts Bay Between 1761 and 1772 at 420 (Boston, Little, Brown & Co.


        1See also 2 Samuel Johnson, A Dictionary of the English Language (4th ed. 1773) (“Inquiry by looking to
every suspected place.”); 2 John Ash, The New and Complete Dictionary of the English Language (2d ed. 1795)
(“An enquiry, an examination, the act of seeking, an enquiry by looking into every suspected place; a question; a
pursuit.”).

1865). In arguing against this sweeping search authority, James Otis contended that customs
officials should not have authority to enter a person’s home and “rifle every part of it.” Essay on
the Writs of Assistance Case, Boston Gazette, Jan. 4, 1762; see 10 Works of John Adams 248 (C.
Adams ed. 1856) (referring to James Otis’s speech denouncing writs of assistance as where “the
child Independence was born”). Others complained that their “houses and even [their] bed
chambers, [were] exposed to be ransacked,” and their “boxes[,] chests & trunks broke open[,]
ravaged and plundered.” Levy, supra, at 166.

       Meanwhile in England, King George III’s Secretary of State, Lord Halifax, began issuing
general warrants to go after the authors, publishers, and printers of newspapers critical of the
English government. Laura Donohue, The Original Fourth Amendment, 83 U. Chi. L. Rev.
1181, 1197, 1201, 1205 (2016). Among dozens of others, John Wilkes, John Entick, and Dryden
Leach were suspects. The King’s messengers went to Wilkes’s home first, walked inside, broke
the locks on his desk drawers, and “rummaged all the papers together they could find.” Wilkes v.
Wood, (1763) 98 Eng. Rep. 489, 491 (K.B.). A few months later, they went to Entick’s home
and searched “all the rooms . . . and all the boxes so broken open, and read over, pryed into, and
examined all [of his] private papers [and] books.” Entick v. Carrington, (1765) 95 Eng. Rep.
275, 275 (K.B.). And finally, they paid Leach a visit and spent six hours searching his home for
his books and papers. Money v. Leach, (1765) 97 Eng. Rep. 1075, 1079 (K.B.). In all three
cases, the King’s messengers were found liable for trespass. Leach, 97 Eng. Rep. at 1089;
Entick, 95 Eng. Rep. at 818; Wilkes, 98 Eng. Rep. at 499. But more importantly, these cases and
the colonies’ growing opposition to writs of assistance provide some context about what the
founding generation envisioned by the term “search”: looking through somebody’s belongings
to find evidence of something illegal. See Kerr, supra, at 72 (“Famous search and seizure cases
leading up to the Fourth Amendment involved physical entries into homes [and] violent
rummaging for incriminating items once inside . . . .”).

       The meaning of “search” at the founding did not change after the United States won
independence. Though the English could no longer search our homes to find uncustomed goods,
Anti-Federalists feared that the federal government would adopt the same oppressive search
practices that England used to collect taxes. In 1788, “A Farmer and Planter” penned an essay
 No. 17-4027                       Morgan v. Fairfield Cty., Ohio                        Page 20


expressing concern that federal excise officers would “break open [their] doors, chests, trunks,
desks, [and] boxes, and rummage [their] house[s] from bottom to top” for goods for which no tax
had been paid. A Farmer and Planter, in 5 The Complete Anti-Federalist 75 (Herbert J. Storing
ed. 1981); see also John DeWitt Letter IV, in 4 The Complete Anti-Federalist at 33;
A Columbian Patriot, in 4 The Complete Anti-Federalist at 278–79. Patrick Henry contended
that tax collectors “may go into your cellars and rooms, and search, ransack, and measure, every
thing [people] eat, drink and wear.” 3 The Debates in the Several State Conventions on the
Adoption of the Federal Constitution 448–49 (Jonathan Elliot ed., 2d ed.1836).

       And after the people ratified the Fourth Amendment to protect against such abuses, early
courts confirmed this understanding of a “search.”        Those courts found that searches had
occurred where officers opened and examined sealed letters or packages, Ex parte Jackson,
96 U.S. 727, 732 (1877), looked through a man’s shop and apartments for jewelry, Larthet v.
Forgay, 2 La. Ann. 524, 525 (La. 1847), poked through a man’s cellar to look for stolen barrels
of flour, Bell v. Clapp, 10 Johns. 263, 265 (N.Y. 1813) (per curiam), and entered a man’s house,
“turned over the beds,” looked through “every hole” and “required every locked place to be
opened,” Simpson v. Smith, 2 Del. Cas. 285, 287 (Del. 1817).

       This history thus shows that when the Framers used the word “search,” they meant
something specific: investigating a suspect’s property with the goal of finding something. See
Katz v. United States, 389 U.S. 347, 367 (1967) (Black, J., dissenting) (“The Fourth Amendment
was aimed directly at the abhorred practice of breaking in, ransacking and searching homes and
other buildings and seizing people’s personal belongings . . . .”). In this way, the original
meaning of the term matches the ordinary one. A “search” under the Fourth Amendment is what
we would intuitively think a search looks like in any other context.

       The Supreme Court’s current Fourth Amendment jurisprudence, however, has taken the
meaning of “search” a step further. Rather than simply asking whether the government engaged
in purposeful, investigative conduct, both of the Court’s prevailing tests add a threshold question
that conflates the search inquiry with the reasonableness one. Start with Katz’s “reasonable
expectation of privacy” test. Id. at 361 (Harlan, J., concurring). Under that framework, the
Court is willing to apply the Fourth Amendment’s protections only if the officers’ conduct
 No. 17-4027                       Morgan v. Fairfield Cty., Ohio                        Page 21


violates a person’s “(subjective) expectation of privacy” that “society is prepared to recognize as
reasonable.” Id. But a search can plainly occur regardless of whether a person reasonably
believes the area the officers rummage through is private. We can see as much from the cases
that apply Katz’s test. Consider California v. Greenwood, where the Court held that an officer
who rifled through a suspect’s garbage to find evidence of drug use did not conduct a search
because the suspect could not reasonably expect the garbage to remain private after putting it out
for collection. 486 U.S. 35, 37–38, 40 (1988). Or consider United States v. Miller, where
officers read through a suspect’s bank records to investigate tax evasion. 425 U.S. 435, 437
(1976). The Court held that no search occurred because the suspect had exposed the records to
the bank’s employees and thus forfeited his privacy in them. Id. at 442.

       In both cases, the jurisprudence is misguided: the officers engaged in a search because
looking through somebody’s garbage or financial records for evidence of a crime is purposeful,
investigative conduct. And whether we think the officers’ conduct was permissible—either
because the suspect abandoned the garbage or shared the bank records with third parties—does
not change that result. Those considerations get at whether the search was reasonable, not
whether a search occurred in the first place. See Carpenter, 138 S. Ct. at 2243 (Thomas, J.,
dissenting) (“[R]easonableness determines the legality of a search, not ‘whether a search . . .
within the meaning of the Constitution has occurred.’” (quoting Minnesota v. Carter, 525 U.S.
83, 97 (1998) (Scalia, J., concurring))); Akhil R. Amar, Fourth Amendment First Principles, 107
Harv. L. Rev. 757, 769 (1994) (“[I]n the landmark Katz case, the Court, perhaps unconsciously,
smuggled reasonableness into the very definition of the Amendment’s trigger . . . .”); see also
William Baude & James Y. Stern, The Positive Law Model of the Fourth Amendment, 129 Harv.
L. Rev. 1821, 1871 (2016) (“The structure of the doctrine is especially puzzling in the Katz
regime, which creates a separate reasonableness analysis at the first step of the Fourth
Amendment framework, prior to evaluating the reasonableness of the government’s conduct at
the second step.”). Smuggling both questions into one is not faithful to the Amendment’s text
and ends up narrowing the scope of its coverage. See Knowlton v. Moore, 178 U.S. 41, 87
(1900) (noting the “elementary canon of construction which requires that effect be given to each
word of the Constitution” (emphasis added)); see also Carpenter, 138 S. Ct. at 2246 (Thomas, J.,

Privacy, or Security?, 33 Wake Forest L. Rev. 307, 331–34 (1998) (listing cases “rejecting any
legitimate expectation of privacy” or finding only a “reduced expectation of privacy” under
Katz).

         After almost five decades of Katz precedent, it became apparent that requiring a
reasonable expectation of privacy pushed too much police conduct outside of Fourth Amendment
scrutiny. So in United States v. Jones, the Court made clear that a litigant’s rights “do not rise or
fall with the Katz formulation” if that formulation does not “assur[e] preservation of that degree
of privacy against government that existed when the Fourth Amendment was adopted.” 565 U.S.
400, 406 (alterations in original) (quoting Kyllo v. United States, 533 U.S. 27, 34 (2001)). The
Court told us that there was another way to determine whether a search occurred: asking
whether the officers “learned what they learned only by physically intruding on [one’s] property
to gather evidence.” Florida v. Jardines, 569 U.S. 1, 9 (2013); see also Jones, 565 U.S. at 405.
This property-based approach is closer to the ordinary and original meaning than Katz. But it,
too, imposes an artificial limit on the meaning of “search.” A search can occur without an
“intrusion” (or as elsewhere described, a “trespass”). Jones, 565 U.S. at 405; see also Kerr,
supra, at 68 (“Neither the original understanding nor Supreme Court doctrine equated searches
with trespass.”). For example, imagine that John Entick invited the King’s messengers into his
house and gave them permission to look through his drawers for his books and papers. Would
anybody contend that the messengers did not search Entick’s home under the ordinary meaning
of the word simply because they were legally present? No. The officers engaged in purposeful
and investigative conduct.     And whether we think the messengers’ conduct is permissible
because Entick authorized them to do it gets at the reasonableness of the search, not whether a
search occurred. Like Katz’s reasonable expectation of privacy test, then, the “intrusion” or
“trespass” question comes at the wrong place in the Fourth Amendment framework.

         If we applied the ordinary and original meaning of the word “search” (and left the
question of reasonableness where it belongs), many things that are currently considered outside
the Amendment’s scope might come back in. As discussed above, rifling through a person’s
garbage and reading through their bank records would both count as a search. See Greenwood,
 No. 17-4027                        Morgan v. Fairfield Cty., Ohio                         Page 23


486 U.S. at 37–38; Miller, 425 U.S. at 437. So too would flying a helicopter four-hundred-feet
over a person’s greenhouse to look through an opening in its roof. See Florida v. Riley, 488 U.S.
445, 448, 450 (1989). As would traipsing through somebody’s farm to look for marijuana or
peering into somebody’s barn with a flashlight to see if they are doing something illegal. See
United States v. Dunn, 480 U.S. 294, 298 (1987); Oliver v. United States, 466 U.S. 170, 173,
179–80 (1984).

       Not only that, but faithfully applying the term’s meaning may make the courts’ initial job
easier. Determining whether somebody has a subjective expectation of privacy that society is
willing to recognize as reasonable leaves much to the “judicial imagination” and often results in
judges deciding “whether a particular practice should be considered a search under the Fourth
Amendment.” Carpenter, 138 S. Ct. at 2264 (Gorsuch, J., dissenting); id. at 2246 (Thomas, J.,
dissenting). As a result, the Court’s precedents applying Katz “bear the hallmarks of subjective
policymaking,” which of course, courts are not equipped (or permitted) to do. Id. at 2246
(Thomas, J., dissenting); see also Carter, 525 U.S. at 97 (Scalia, J., concurring) (pointing out that
“unsurprisingly, those ‘actual (subjective) expectation[s] of privacy’ ‘that society is prepared to
recognize as reasonable,’ bear an uncanny resemblance to those expectations of privacy that this
Court considers reasonable” (alterations in original) (quoting Katz, 389 U.S. at 361 (Harlan, J.,
concurring))). Asking whether an officer engaged in a purposeful, investigative act brings courts
back into their wheelhouse: analyzing the facts before them.

       Returning to the original meaning would also eliminate the property-based approach’s
threshold question—whether there was an intrusion or trespass—simplifying the initial search
inquiry. The Court’s decision in Kyllo v. United States shows why. 533 U.S. at 27. There, the
Court had to decide whether officers conducted a search when they used a thermal imager to
scan the outside of a home for heat signatures. Id. at 29–30. One possible answer could have
been no. The Court had long held that “naked-eye surveillance of a home” did not amount to a
search because “the eye cannot . . . be guilty of trespass.” Id. at 31–33 (internal quotation marks
omitted). But the case at hand presented something different: the officers were using more than
their naked eye yet doing something short of common law trespass. Id. To thread the needle, the
Court held that “obtaining by sense-enhancing technology any information regarding the interior
 No. 17-4027                       Morgan v. Fairfield Cty., Ohio                       Page 24


of the home that could not have been obtained without physical intrusion into a constitutionally-
protected area constitutes a search—at least where (as here) the technology in question is not in
general public use.” Id. at 34 (internal quotations and citation omitted). What to do if the
technology is in general public use, the Court has not said. And how to go about analogizing
ever-evolving technology to on-foot search techniques will likely prove more difficult than the
Court envisions.    Under the ordinary and original meaning of “search,” however, neither
question arises. The officers conducted a search in Kyllo because using a thermal imager to
determine whether heat is emanating from a house is a purposeful, investigative act.

       A “search” under the Fourth Amendment is thus easier to identify when we are faithful to
the ordinary and original meaning of the term, and the concept is broader than the Court’s
current jurisprudence contemplates.

                                               II.

       This brings me to the case at hand. The Fairfield County police received two anonymous
tips that Morgan and Graf grew marijuana and cooked methamphetamine in their house. So five
officers went to their home for a “knock and talk,” a police tactic where an officer walks up to
the front door of a house and seeks to speak with a suspect and/or gain consent for a search.
Consistent with county policy, two officers walked up to the front door, and the rest surrounded
the perimeter of the house, standing five-to-seven feet from its exterior. One officer went around
back and noticed marijuana plants growing on Morgan and Graf’s second-story deck. With this
information, the officers secured a warrant to search inside the home. Now Morgan and Graf
contend that when the officers surrounded the home, they engaged in an unreasonable search in
violation of the Fourth Amendment.

       The City Policy. Let’s start with the policy. The question before the court is whether the
policy directed officers to violate Morgan and Graf’s rights. The answer under both current
doctrine and the original meaning is no.

       In Jardines, the Supreme Court held that an unreasonable Fourth Amendment search
occurs when an officer intrudes a constitutionally-protected zone, i.e., the house, to gather
 No. 17-4027                        Morgan v. Fairfield Cty., Ohio                       Page 25


evidence. See 569 U.S. at 6. So, to be unconstitutional, the policy must direct officers (1) to
enter a constitutionally protected zone, and (2) to gather evidence. Id. at 9.

       Here, the majority is correct that the policy directed officers to enter a constitutionally-
protected zone. Morgan and Graf have a right to be secure in their home, which includes the
curtilage of the home. See id. at 6 (noting that “curtilage” is the area “immediately surrounding
and associated with” a house); Amos v. United States, 255 U.S. 313, 314, 346 (1921); see also
Dunn, 480 U.S. at 294 ; Oliver, 466 U.S. at 180; 4 William Blackstone, Commentaries on the
Laws of England *225 (noting that the “capital house protects and privileges all its branches and
appurtenants, if within the curtilage”). Since the county policy required the officers to go “onto
the back of the property” and generally be within “five-to-seven feet” of the house, it directed
them to enter the curtilage. R. 45-7, Pg. ID 542; R. 45-6, Pg. ID 533.

       But the county policy did not direct officers to gather information while there. As such,
there is no search. See Jardines, 569 U.S. at 6 (holding that to be a search officers must gather
information while in the protected zone); see also Collins v. Virginia, 138 S. Ct. 1663, 1670
(2018) (“When a law enforcement officer physically intrudes on the curtilage to gather evidence,
a search within the meaning of the Fourth Amendment has occurred.” (emphasis added)); Jones,
565 U.S. at 406 n.3. For if an officer is trick-or-treating with their kids in the constitutionally
protected zone, it is not a Fourth Amendment problem. Nor is it a problem if an officer is
“approaching your home to return your lost dog or to solicit for charity.” United States v.
Carloss, 818 F.3d 988, 1005 (10th Cir. 2016) (Gorsuch, J., dissenting). The officer must engage
in some sort of investigation to implicate the Fourth Amendment’s protections.           Jardines,
569 U.S. at 6. Yet the county policy directing officers to secure the perimeter is designed to do
one thing: ensure officer safety. As the officers testified, whenever they conduct a knock and
talk, there is a risk that the officer knocking on the front door “could be ambushed by somebody
coming out of the back door.” R. 45-6, Pg. ID 525. Or a dangerous individual might flee the
residence. And since the officers suspected that Morgan might have been dangerous, the policy
required an officer to stand at every corner of the house. If the policy had required the officers
surrounding the house to also investigate while there, the county would be directing the officers
to violate the Fourth Amendment. But the county’s policy was silent as to any information-
 No. 17-4027                              Morgan v. Fairfield Cty., Ohio                                   Page 26


gathering mandate for the officers. As such, the policy itself did not direct the officers to violate
the Fourth Amendment.

         Similarly, when analyzing the policy under the original meaning, the answer is the same.
But the first question is different. Whereas the property-based approach asks whether the
officers were in a constitutionally-protected zone, the original meaning asks if those officers
were conducting a search. The key inquiry is not whether officers conduct a search while in the
protected area, but rather whether they conduct a search of the protected area. See infra Part I.
While this distinction may lead to different outcomes in other cases, in Morgan and Graf’s case it
does not. Here the county’s policy did not direct officers to engage in a purposeful, investigative
act of Morgan and Graf’s home. Accordingly, since there was no search directed by the policy,
no constitutional violation occurred under the original meaning of the Fourth Amendment.2

         The officers. Turning to the officers, I agree with the majority that the constitutional
violation was not clearly established. But, if I was writing on a clean slate, I would remand.
And the question I would direct the district court to answer is whether the officers engaged in a
purposeful, investigative act to find the marijuana plants.

                                                         III.

         As the county’s policy did not direct a search in Morgan and Graf’s case (and the original
meaning approach to the Fourth Amendment would require a remand to determine whether the


         2That   is, of course, not to say that police officers should be allowed to run roughshod over people’s
property so long as a court does not determine that they conducted a search. The officers in this case could be liable
for trespass. Under Ohio law, no person is permitted to “[k]nowingly enter or remain on the land or premises of
another.” Ohio Rev. Code Ann. § 2911.21(A)(1) (criminal trespass statute). And though the officer at the front
door was permitted to walk up to the house and knock without violating the law, the other officers were not allowed
to use his lawful presence as a gateway to the rest of his property. See Gladon v. Greater Cleveland Reg’l Transit
Auth., 662 N.E.2d 287, 292 (Ohio 1996) (“If the invitee goes outside the area of his invitation, he becomes a
trespasser or a licensee, depending upon whether he goes there without the consent of the possessor, or with such
consent.” (quoting Restatement (Second) of Torts § 332 (Am. Law Inst. 1965))). Ohio immunity may ultimately bar
such a suit, but should practices become sufficiently egregious, the people of Ohio could change whether immunity
applies. Indeed, private tort suits against officers used to be the only mechanism to assert a Fourth Amendment
right—the exclusionary rule, Section 1983, and Bivens actions did not yet exist. See Collins, 138 S. Ct. at 1676
(Thomas, J., concurring) (“Historically, the only remedies for unconstitutional searches and seizures were ‘tort suits’
and ‘self-help.’”); Gardner v. Neil, 4 N.C. 104, 104 (1814); Akhil R. Amar, The Bill of Rights 69 (1998) (noting that
the “paradigmatic way in which Fourth Amendment rights were to be enforced” was through civil suits under
common law tort claims).

officers in fact “searched”), the court need not go further. If there had been a search, however,
then I would continue to adhere to a Fourth Amendment analysis guided by the Amendment’s
text and its original meaning. To do this analysis, ordinarily the court would need to look at the
contours of the constitutionally-protected zones—persons, houses, papers, and effects.
U.S. Const. amend. IV; see, e.g., Maureen E. Brady, The Lost “Effects” of the Fourth
Amendment: Giving Personal Property Due Protection, 125 Yale L.J. 946, 987 (2016). Such an
analysis would not prove difficult here as the marijuana plants were squarely within a
constitutionally-protected zone, i.e., on the back-deck within the house’s curtilage.3 The court
would also need to decide the appropriate source of law to determine when a person is “secure
in” one of those constitutionally-protected zones.              See Carpenter, 138 S. Ct. at 2241–42
(Thomas, J., dissenting); id. at 2269 (Gorsuch, J., dissenting). For instance, similar to the Fifth
and Fourteenth Amendments, should courts look to state property law to determine what rights
someone has in the constitutionally-protected zone? See Baude & Stern, supra, at 1842–43
(suggesting courts look to existing law (usually state) to determine constitutional protections);
Richard Re, The Positive Law Floor, 129 Harv. L. Rev. F. 313, 332 (2016) (“[W]hen lawmakers
guard against privacy intrusions by private parties, then similar intrusions by the government
would be presumptively unreasonable.”). And, of course, the court must grapple with the
appropriate meaning and function of the term “unreasonable.” While strong evidence suggests
that “unreasonable” should be understood as “against the common law,” there is evidence that
the original public meaning may have been broader. Compare Donahue, supra, at 1192 (arguing
that “unreasonable” means “against the common law”), with David A. Sklansky, The Fourth
Amendment and Common Law, 100 Colum. L. Rev. 1739, 1778–84 (2000) (describing that
“unreasonable” may have encompassed more than “against the common law”). Some of these
inquiries might prove relatively easy, while others are certainly hard. But, luckily, judges are
aided in this endeavor by the contributions of very astute scholars. And in the end, courts and
parties will benefit from thoughtful briefing and scholarship that brings clarity to the Fourth



        3Though  not presented by this case, how ever-changing technology fits within the contours of these zones
may continue to challenge courts. See Orin S. Kerr, The Fourth Amendment and New Technologies: Constitutional
Myths and the Case for Caution, 102 Mich. L. Rev. 801, 807 (2004) (arguing that “regulating developing
technology through the Fourth Amendment poses significant difficulties for courts”).
