O P I N I O N

	In this felony prosecution for possession of ecstasy, the State appealed from the trial
court's grant of the appellee's motion to suppress evidence that the appellee contended was
obtained as a result of an illegal traffic stop.  The El Paso Court of Appeals affirmed the trial
court's ruling in an unpublished opinion, holding that the appellee's initial detention was
illegal and that the taint emanating from the initial illegality was not attenuated by the fact
that, immediately after the initial stop, the appellee was found to have an outstanding arrest
warrant that might give rise to a valid search incident to arrest. (1)  We granted the State's
petition for discretionary review to examine this holding and now reverse.
FACTS AND PROCEDURAL POSTURE
Motion to Suppress
	The appellee was indicted for the offense of possession with intent to deliver more
than four but less than 400 grams of methylenedioxy methamphetamine, popularly known
as ecstasy, a first degree felony offense. (2)  Prior to trial, the appellee filed a motion to suppress
evidence stemming from his initial detention in this case.  At a pre-trial hearing on March
19, 2009, the State's only witness was the arresting officer, El Paso Police Officer
Christopher Grijalva.
	Grijalva testified that, on December 11, 2008, he was assigned to patrol the Sunland
Park Mall area on the west side of El Paso, along with his partner, Officer Mike Chavez. 
Grijalva and Chavez were part of the Westside Regional Command Center TAC patrol, a unit
that does not respond to routine patrol calls but instead performs specific assignments.  On
this particular day, the TAC patrol was tasked with looking for traffic violators.  At
approximately 10:00 p.m., the officers were conducting a separate traffic stop when Grijalva
noticed a yellow Mustang that pulled into the parking lot of the mall with what Grijalva
perceived to be defective taillights.  The taillights appeared to Grijalva to emit white light,
whereas by statute they should be red. (3)  Once they completed their traffic stop, Grijalva and
Chavez once again observed the yellow Mustang, now parked in the mall parking lot.  At
around 10:20 p.m., they observed the Mustang begin to move again.  After alerting other
members of the TAC patrol, they stopped it for the perceived taillight infraction.  They had
no other reason to stop the Mustang--they did not suspect the occupants of any other crime,
nor were they aware that the occupants might be the subject of any outstanding warrants.
	While Chavez checked the driver's identification and proof of financial responsibility,
Grijalva approached the passenger side of the Mustang, where the appellee sat, and asked the
appellee for identification.  Without speaking, the appellee produced a driver's license, and
both Chavez and Grijalva returned to their squad car to check for outstanding warrants. 
When their computer showed that the appellee had at least a pair of outstanding warrants,
they contacted the warrants office and confirmed that the warrants were active. (4)  Grijalva
returned to the passenger side of the Mustang and asked the appellee to step out.  When the
appellee complied, Grijalva asked him whether he was aware that he had outstanding
warrants, to which the appellee "kind of looked at [Grijalva] and then said yes, I know I have
warrants."  Grijalva then "escorted" the appellee to the squad car and "asked him to put his
hands on the vehicle."  Intending to pat the appellee down for safety purposes, Grijalva first
"asked him if he had anything illegal on him, any weapons or anything else.  At which point
he stated yes, he did."  When Grijalva asked him what he had, the appellee answered that
there was ecstasy in a black pouch in his right front pants pocket.  Grijalva subsequently
"placed [the appellee] into custody," patted him down, discovered and seized the ecstasy as
well as a small baggie of marijuana, and then put the appellee in the back seat of the squad
car.  The appellee volunteered that the Mustang belonged to his cousin, and that there was
"a black zippered bag under the front passenger seat" that did not belong to his cousin. 
Grijalva retrieved the bag and found that it contained additional baggies of marijuana.
	The owner and driver of the Mustang, Isaac Medina, testified for the defense at the
motion to suppress hearing.  Five years before the traffic stop he had modified his taillights
to include "some clear rear lights," but they retained "red lights in the middle[.]"  Medina had
never before gotten a ticket, and the car had always passed the annual state inspection.  He
denied that his Mustang ever "had any white or - any white emitting taillights."  Photographs
of the rear of the Mustang were introduced into evidence showing the condition of the
taillights as of the time of the traffic stop.  The State then recalled Grijalva to the stand and
showed him the photographs, which were taken in daylight.  Grijalva maintained that the
taillights looked much different when illuminated at night.  Asked whether, on the night of
the stop, "there was any red emminating [sic] from those . . . taillights?", he replied: "There
was mostly white.  From what I distinctly saw it was mostly white.  I don't recall if we got
close and saw that there was any red.  But the white dominated the red color."
	Counsel for appellee urged the trial court to discount Grijalva's testimony.
		[DEFENSE COUNSEL]: Your Honor, I believe that the Court has the
photographs of the taillights in front of him.  And as you see the taillights have
a clear casing.  The bulbs themselves are red.  You can see that.  You have
them in front of you.  The light would either be red or not lit at all.  And I think
the officer's testimony to the contrary is not credible and not believable. (5)

For her part, the prosecutor reminded the trial court that the photographs had been taken in
daylight and that Grijalva had observed them at night.  She argued, alternatively, that even
if the stop was illegal, "there is case law out there that states that if there is a warrant out for
the defendant, an illegal stop doesn't taint the warrants for the arrest." (6)  The trial court asked
the prosecutor to produce those cases and took the matter under advisement.
Trial Court's Findings and Conclusions
	On March 25, 2009, the trial court signed an order granting the appellee's motion to
suppress but did not enter findings of fact and conclusions of law.  That same day, the State
filed a request for findings of fact and conclusions of law. (7)  On April 9, 2009, the trial court
duly entered written findings and conclusions. (8)  Those findings and conclusions, in relevant
part, read:
findings of fact:
	1.	On December 11, 2008, at approximately 10:20 p.m. Officer Grijalva
and Officer Chavez of the El Paso Police Department detained a yellow
Mustang vehicle in the parking lot of the Linens n Things on the
Westside of El Paso, Texas.

	2.	The trial court having heard the testimony and having evaluated the
demeanor of the witnesses finds that Officer Chavez's [sic: Grijalva]
testimony that he had a reasonable belief that Transportation Code
547.322 had been violated to not be credible.

	3.	The trial court having heard the testimony and having evaluated the
demeanor of the witnesses finds that Officer Chavez [sic] did not have
a reasonable belief that the yellow Mustang had white lights to the rear.

	4.	The trial court having evaluated and heard the testimony of Isaac
Medina finds his testimony to be credible and that the photographs
admitted as Defense exhibits 1-6 fairly and accurately depict the vehicle
and [its] lights as they appeared when the vehicle was stopped on
December 11, 2008.

* * *

	7.	The trial court finds that [the] yellow Mustang's [taillights] emitted red
light on December 11, 2008.

* * *

	11.	The trial court having evaluated the credibility of the witnesses finds
that there was no other reason for the detained [sic] of the vehicle other
than white lights to the rear.

* * *

	14.	The trial court finds that [the appellee] was not read his Miranda
warnings.

	15.	The trial court finds that the questioning of [the appellee] and the
discovery of contraband were not only in close temporal proximity but
were in fact almost simultaneous.

* * *

	17.	The trial court finds that [the appellee] did not volunteer any
information but rather answered the [officer's] questions when he
provided his identifying information.

	18.	The trial court finds that [the appellee] was not free to leave from the
time that the yellow Mustang that he was a passenger in was detained.

	19.	The trial court finds that [the appellee] was placed under arrest for
outstanding warrants after he was detained and questioned by Officer
Chavez [sic] after being a passenger in the yellow [M]ustang that was
detained by Officer Chavez and Officer Grijalva.

conclusions of law[:]

	1.	The driver of the Mustang did not violate Section 547.322 of the
Transportation Code on December 11, 2008.

	2.	The Police Officers did not have probable cause or reasonable
suspicion to perform a traffic stop on that date.

	3.	The arrest warrants of the Defendant did not purge the taint of the
illegal stops due to the flagrancy of the police action, the close temporal
proximity and the fact that no Miranda warnings were read.

From these findings and conclusions, the State appealed. (9)
On Appeal
	The court of appeals deferred to the trial court's credibility determination with respect
to Grijalva's testimony regarding the basis of the stop and held accordingly that the arresting
officers "lacked justification to make the stop at its inception because the car's taillights were
not white, as the officer testified." (10)  Proceeding to the question whether the taint from that
illegal stop may have been attenuated by Grijalva's immediate discovery of the outstanding
arrest warrants, the court of appeals acknowledged case law from this Court and other courts
of appeals holding "that the discovery of a valid warrant, even in a situation involving an
illegal detention, breaks the connection between the primary taint and the subsequently
discovered evidence." (11)  Nevertheless, to hold that the discovery of the appellee's arrest
warrants dissipated the taint of the unlawful stop on the facts of this case, the court of appeals
observed, would serve only to "encourage the seizure of suspects upon inadequate grounds
while an investigation is conducted for the purpose of establishing probable cause or
discovering the existence of search warrants." (12)  For this reason, the court of appeals rejected
the State's argument that Grijalva's discovery of the appellee's outstanding traffic warrants
purged the taint of the primary illegality of the initial stop. (13)  We granted the State's petition
for discretionary review to address its contention that this holding conflicts with this Court's
opinion in Johnson v. State, (14) and, more pointedly, with the holdings of several other courts
of appeals in Texas. (15)
THE ATTENUATION OF TAINT DOCTRINE
Wong Sun and Johnson
	The Fourth Amendment exclusionary rule exclusively serves a function of  deterrence,
to discourage undue police encroachment upon the privacy and personal integrity of the
citizenry. (16)  Because of the substantial social costs involved in exercising this deterrent
function, however, application of the exclusionary rule should operate as a "last resort," not
a "first impulse." (17)  Accordingly, not every Fourth Amendment violation necessarily results
in the suppression of evidence just because, but for that violation, the evidence would never
have been exposed.  As the Supreme Court observed in Wong Sun v. United States:
	We need not hold that all evidence is "fruit of the poisonous tree" simply
because it would not have come to light but for the illegal actions of the police. 
Rather, the more apt question is "whether, granting establishment of the
primary illegality, the evidence to which instant objection is made has been
come at by exploitation of that illegality or instead by means sufficiently
distinguishable to be purged of the primary taint." (18)

We expressly invoked this attenuation of taint principle in Johnson. (19)
	Johnson was arrested without a warrant and, he contended, without probable cause. (20) 
When the arresting officer transported Johnson to the police station, he discovered an
outstanding warrant for his arrest emanating from another county. (21)  Subsequent to the
discovery of the arrest warrant, Johnson was photographed, and the photograph was used in
a photographic line-up from which the victim of the robbery for which Johnson was
prosecuted was able to identify him. (22)  In a motion to suppress, Johnson challenged the
admissibility of the photographic identification, his contention being that the photograph
used was the product of the illegality stemming from his initial unlawful arrest. (23)  We
rejected this contention on direct appeal, holding that, "[e]ven if the arrest was illegal, it
would appear that [Johnson's] detention at the time of the picture taking was not illegal." (24) 
We went on to conclude that the "identification testimony would have been obtained
regardless by means sufficiently distinguishable from the underlying illegality to be purged
of the primary taint[,]" citing for authority the above passage from Wong Sun. (25)
Brown v. Illinois
	Two years after Johnson, the Supreme Court elaborated upon Wong Sun and the
attenuation of taint doctrine in Brown v. Illinois. (26)  Brown was arrested "without probable
cause and without a warrant." (27)  The arresting officers took him to the police station for
interrogation, issuing him his Miranda warnings at the outset. (28)  On appeal, Brown argued
that the resulting confession should have been suppressed at trial under the Fourth
Amendment because it was the product of his illegal arrest. (29)  The Illinois Supreme Court
disagreed, holding that the taint of the primary illegality was attenuated when the offending
officers issued Brown his Miranda warnings before taking his confession, thus assuring its
voluntariness. (30)  Carefully delineating Fourth and Fifth Amendment rights, however, the
Supreme Court reversed, holding that, by themselves, Miranda warnings cannot serve as an
intervening event sufficient to purge the illegality of an unconstitutional arrest for purposes
of applying the Fourth Amendment exclusionary rule. (31)  While the presence or absence of
Miranda warnings and the apparent voluntariness of the confession are certainly factors for
courts to consider in determining whether suppression is required, they are by no means the
only factors. (32)  In addition, "[t]he temporal proximity of the arrest and the confession, the
presence of intervening circumstances, and, particularly, the purpose and flagrancy of the
official misconduct are all relevant." (33)  Applying these factors, the Supreme Court concluded
that Brown's confession should have been suppressed. (34)
	The instant case involves the proper application of the attenuation of taint doctrine,
not to a confession, as in Brown, but to contraband that is seized immediately following an
unconstitutional detention or arrest.  Will the discovery of an outstanding arrest warrant in
the relatively few moments that ensue between the illegal stop and the seizure of the
contraband invariably serve as an intervening event sufficient to purge the taint of the
primary illegality?  In our opinion last year in State v. Elias, we observed that "this Court has
yet to directly weigh in on this issue," (35) at least since Johnson, and then Brown, were
decided.  But a number of courts of appeals in Texas have, as have many other jurisdictions
across the country.
The Courts of Appeals in Texas
	In a line of cases spanning the last twenty years, several courts of appeals in Texas
have held that the discovery of an arrest warrant, after an illegal detention or arrest but before
the consequent discovery and seizure of contraband, "may" serve to break the causal
connection between the initial illegality and the subsequent seizure so as to purge the primary
taint.  The first and most comprehensively reasoned opinion in this line of cases is that of the
Dallas Court of Appeals in Reed v. State. (36) Characterizing the issue as one "of first
impression" in Texas, (37)  the court of appeals in Reed boiled it down as follows.
	[W]hether, when during the course of an illegal detention of appellant for the
stated purpose of determining appellant's identity, a valid warrant for the arrest
of appellant was discovered upon establishing appellant's identity and
appellant was arrested under authority of that warrant, contraband found
during the subsequent book-in inventory search is admissible into evidence
against appellant because the existence of the warrant sufficiently attenuates
the connection between the illegal detention and the discovery of the
contraband. (38)

While acknowledging this Court's opinion in Johnson, the Reed court proceeded to resolve
this issue specifically by reference to the attenuation factors identified in Brown, excluding
the question of whether Reed received Miranda warnings (presumably because the case did
not involve the attempted suppression of a confession, but only of contraband).
	Addressing the temporal-proximity factor first, the court of appeals observed:
		In the present case, we conclude that the temporal proximity between
the first illegal arrest and the second legal arrest does not bear on the
attenuation.  This factor has been cited and considered exclusively in cases
where confessions or statements were obtained from a suspect subsequent to
an illegal arrest.  We also reason that, unlike the confession cases, where the
statements can be seen as a psychological product of the arrest, the diminution
of the likelihood of the discovery of physical evidence as a result of the illegal
arrest cannot be a function of the passage of time.  Thus, we conclude that the
temporal proximity factor is of no moment in this case. (39)

Turning next to the intervening-circumstances factor, the Reed court held "that Johnson
stands for the proposition that discovery of an outstanding warrant during an illegal detention
of an individual breaks the connection between the discovered evidence and the primary
taint." (40)  Notwithstanding the seemingly determinative nature of this holding, the court of
appeals nevertheless went on to address the purpose and flagrancy of the police misconduct
as well, finding "nothing in the record that indicates that the transportation of appellant to
the identification section [of the police department] was done for the purpose of . . .
providing a pretext for a search." (41)  Having found both an intervening event and the absence
of any purposeful or flagrant police misconduct, the court of appeals held that the trial court
properly denied Reed's motion to suppress. (42)
	Since Reed was decided, a number of other court of appeals opinions have cited it as
authority for the proposition that the intervention of a valid arrest warrant between an illegal
arrest or detention and the subsequent discovery and seizure of contraband will suffice to
attenuate the taint of the primary illegality. (43)  Unlike Reed, however, these subsequent court
of appeals opinions seem to turn exclusively on the intervening-circumstance factor, as if that
factor alone were categorically sufficient to establish attenuation, without any need to
incorporate the purpose-and-flagrancy factor into the analysis. (44)  Although this Court has yet
to address the question of which of the Brown factors should apply in this context, and how
they should apply, the highest courts in a number of other jurisdictions have.
Other Jurisdictions
	Practically every other jurisdiction to address the question of attenuation of taint to
the illegal seizure of physical evidence has deemed it appropriate to apply three of the Brown
factors (45)--temporal proximity, intervening circumstances, and the purposefulness or
flagrancy of the police misconduct--albeit with variable emphases.  For example, while no
other court since Reed has declared temporal proximity wholly irrelevant, many courts have
downplayed its significance, particularly when the discovery of an arrest warrant separates
an initial illegal stop from the seizure of contraband. (46)  Other courts have tended, like our
own courts of appeals after Reed, to briefly mention all three of the Brown factors while
highlighting the intervening circumstance factor--namely, the interceding discovery of an
arrest warrant--as practically determinative of attenuation. (47)  But the latest trend seems to
be for courts to downplay both the temporal proximity factor and, to a lesser extent, the
intervening circumstance factor in preference to the purposefulness-and-flagrancy factor,
reasoning that it is this third factor that most directly serves the policy of deterrence that fuels
the exclusionary rule in the first place. (48)  We favor this emerging trend.
	Illustrative of the trend is last year's opinion of the Arizona Supreme Court in State
v. Hummons. (49)  At trial, Hummons claimed that certain contraband seized from his person
should be suppressed because it was the product of an illegal detention. (50)  The trial court
denied the motion to suppress, holding that the stop had constituted a consensual encounter,
not a detention sufficient to trigger Fourth Amendment concerns. (51)  The intermediate
appellate court affirmed, but on a different basis, declaring that, even if Hummons was
illegally detained, the subsequent search of his backpack that exposed the contraband
occurred only after the arresting officer discovered that Hummons had an outstanding arrest
warrant. (52)  The Arizona Supreme Court granted review of the intermediate court's attenuation
of taint analysis. (53)
	Applying the three attenuation factors from Brown, the Arizona Supreme Court agreed
with the intermediate court that the temporal proximity factor favored suppression, since the
seizure of the contraband occurred within a few minutes of the stop. (54)  But it also agreed with
the lower court's assessment that "this is the least important Brown factor." (55)  The Hummons
court next confirmed the lower court's conclusion that the discovery of the arrest warrant
indeed qualified as an intervening circumstance. (56)  But it found that the lower court had erred
to regard this factor as essentially determinative in itself, observing that the intermediate
court had
	overemphasized the importance of the warrant as an intervening circumstance
in attenuating an illegal detention's taint upon evidence discovered in a search
incident to arrest.  If the purpose of an illegal stop or seizure is to discover a
warrant--in essence, to discover an intervening circumstance--the fact that a
warrant is actually discovered cannot validate admission of the evidence that
is the fruit of the illegality.

		If, as the court of appeals suggested, a warrant automatically dissipated
the taint of illegality, law enforcement could then create a new form of police
investigation by routinely illegally seizing individuals, knowing that the
subsequent discovery of a warrant would provide after-the-fact justification for
illegal conduct. (57)

For this reason, the Arizona Supreme Court determined that "the subsequent discovery of a
warrant is of minimal importance" in the attenuation of taint analysis. (58)
	By contrast, "[t]he purpose and flagrancy of illegal conduct, the third Brown factor,
. . . goes to the very heart and purpose of the exclusionary rule." (59)  Noting that Brown itself
had deemed the third factor "particularly" important, (60) the Hummons court observed:
	Factors such as an officer's regular practice and routines, an officer's reason
for initiating the encounter, the clarity of the law forbidding the illegal
conduct, and the objective appearance of consent may all be important in this
inquiry.  By focusing on officer conduct, courts may distinguish between
ordinary encounters that happen to devolve into illegal seizures and
intentionally illegal seizures for the purpose of discovering warrants. (61)

Applying the three Brown factors as thus prioritized, the Arizona Supreme Court found that
any taint from the initial stop was attenuated, focusing particularly on the lack of any
evidence in the record to suggest that the detaining officer had deliberately made the stop in
the hope of revealing an outstanding arrest warrant that would justify a search. (62)
Conclusion
	We agree with the Arizona Supreme Court's general assessment.  In our view, the first
Brown factor is certainly relevant, (63) but, even though it usually favors suppression of
evidence that is discovered in the immediate aftermath of an illegal pedestrian or roadside
stop, it will sometimes prove to be, in the context of the seizure of physical evidence, "the
least important factor"--at least relative to the other two.  And while we are hesitant to
confirm as a categorical matter that the intervening circumstance of a valid arrest warrant is
"of minimal importance"--after all, without it, there can usually be no attenuation of taint
when physical evidence is unearthed immediately after an illegal stop--we agree that it
should not be overemphasized to the ultimate detriment to the goal of deterrence that
animates the exclusionary rule.  Finally, we agree that the more important factor is the
purposefulness and flagrancy, vel non, of the primary illegal conduct--whether the police
have deliberately perpetrated what they know to be an illegal stop in the specific hope or
expectation that it will generate some legitimate after-the-fact justification to arrest and/or
search, or they have otherwise conducted themselves in particularly egregious disregard of
the right to privacy and/or personal integrity that the Fourth Amendment protects.  For, when
this is the case, to admit the physical evidence because of the fortuity that an arrest warrant
happens to come to light before the evidence is discovered perversely serves to encourage,
rather than discourage, official misconduct and renders the Fourth Amendment toothless.
	To summarize: When police find and seize physical evidence shortly after an illegal
stop, in the absence of the discovery of an outstanding arrest warrant in between, that
physical evidence should ordinarily be suppressed, even if the police misconduct is not
highly purposeful or flagrantly abusive of Fourth Amendment rights.  Under this scenario,
temporal proximity is the paramount factor.  But when an outstanding arrest warrant is
discovered between the illegal stop and the seizure of physical evidence, the importance of
the temporal proximity factor decreases.  Under this scenario, the intervening circumstance
is a necessary but never, by itself, wholly determinative factor in the attenuation calculation,
and the purposefulness and/or flagrancy of the police misconduct, vel non, becomes of vital
importance.  To the extent that our pre-Brown analysis on direct appeal in Johnson placed
practically exclusive emphasis on the intervening circumstance of an arrest warrant to justify
the admission of evidence following an illegal stop, we disapprove it. (64)
ANALYSIS
Standard of Review
	In the instant case, at the State's request, the trial court entered express written
findings of fact and conclusions of law with respect to the appellee's motion to suppress. (65) 
In reviewing the trial court's ultimate ruling on a motion to suppress, an appellate court must
give "almost total deference" to the trial court's resolution of issues of historical fact and to
its assessment of the weight and credibility of the testimony. (66)  But, once having resolved all
questions of historical fact and weight and credibility of the testimony in the light most
favorable to the trial court's resolution of the legal issues, (67) an appellate court then conducts
a de novo review of the proper application of law to the factual disputes and credibility issues
as thus resolved, in order to say whether the trial judge has reached the correct legal
conclusion with respect to "the legal significance of the facts he has found." (68)
	Here, the trial court found as a matter of historical fact that "the yellow Mustang's tail
lights emitted red light" at the time of the stop, and it refused to give credence to Grijalva's
testimony at the suppression hearing that he had "had a reasonable belief" that a traffic code
violation had occurred.  The State does not now contend that the trial court's historical
finding of fact and its credibility determination are unsupported by the record and does not,
at this stage, contest the trial court's consequent legal conclusion that the police "did not have
probable cause or reasonable suspicion to perform a traffic stop" of the Mustang in which
the appellee was a passenger.  We therefore take this legal conclusion as a given and turn to
the question whether the trial court properly applied the doctrine of attenuation of taint to the
facts of the case to determine whether the unlawful stop should have resulted in suppression
of the ecstasy found in the appellee's pocket.
Application of Law to Facts
	Grijalva found the ecstacy in the appellee's pants pocket and seized it within minutes
of the illegal stop--but not before first determining that the appellee had at least two
outstanding arrest warrants and confirming that they were active.  Thus, while the trial court
was correct to conclude that the temporal proximity of the seizure of the ecstasy to the illegal
stop supports suppression, that factor does not weigh very heavily in light of the intervening
circumstance of the discovery of the valid arrest warrants. (69)  The trial court also concluded
that "the flagrancy of the police action" weighed in favor of suppression, but it made no
findings of fact tailored to this conclusion.  And indeed, the record is not particularly well
developed with respect to this issue. (70)  But what evidence there is in the record was
undisputed and did not, in our view, support the trial court's application of the law to the
facts.
	As to purposefulness, the record shows that Grijalva and Chavez were part of a unit
specifically tasked on that day with looking for traffic violators.  There is no indication that
they were making traffic stops for any purpose other than to enforce the traffic laws or that
they harbored the specific hope or expectation that they might obtain the consent of motorists
to search their vehicles or identify motorists with outstanding arrest warrants so that they
might conduct searches incident to arrest.  Nor does the record support a conclusion that
Grijalva's conduct during the course of this concededly illegal traffic stop was flagrantly in
derogation of the appellee's Fourth Amendment rights. (71)  Grijalva did not demand that the
appellee, a passenger in the car, supply identification; he merely asked for it.  Once the
appellee assented to provide that information, (72) Grijalva immediately conducted a check for
warrants, as he was entitled to do during a routine traffic stop, so long as that warrant check
does not extend the legitimate duration of the traffic stop beyond the scope of its original
justification. (73)  So, while the initial stop itself was illegal, Grijalva never went beyond the
bounds of what would have been constitutionally permissible had the stop in fact been
justified at its inception.  Under these circumstances, applying the law, as we have explicated
it in this opinion, to the undisputed facts of the case in our de novo review, we conclude that
the behavior of the arresting officers, although clearly unlawful at the outset, was not so
particularly purposeful and flagrant that the discovery of the appellee's outstanding arrest
warrants may not serve to break the causal connection between the illegal stop and the
discovery of the ecstasy in the appellee's pants pocket, thus purging the primary taint.  We
hold that the trial court erred to conclude otherwise.
	The court of appeals nevertheless affirmed the judgment of the trial court out of what
it deemed an overriding concern that a contrary ruling would "encourage" the police to
undertake unlawful stops on a pretext, "for the purpose of establishing probable cause or
discovering the existence of arrest warrants." (74)  We certainly share that concern.  However,
we think that prioritizing the purposefulness and flagrancy factor satisfactorily addresses that
concern without fashioning a rule that would altogether remove the intervening discovery of
an arrest warrant as a factor relevant to the attenuation of taint analysis, as the court of
appeals opinion tended to do.  The court of appeals adopted an approach that would
effectively presume purposeful and/or flagrant police misconduct from the fact of the
primary illegality alone rather than assessing the character of that illegality, and of any
subsequent police conduct, to determine whether it indicates that they actually behaved
purposefully or flagrantly in the particular case.  We hold that the court of appeals erred to
rely upon this de facto presumption to affirm the trial court's ruling on the appellee's motion
to suppress.  Applying the appropriate analysis today, we hold that the trial court should have
denied that motion.
CONCLUSION
	Accordingly, we reverse the judgment of the court of appeals.  We remand the cause
to the trial court for further proceedings consistent with this opinion.

1. 	 State v. Mazuca, No. 08-09-00102-CR, 2011 WL 1533419 (Tex. App.--El Paso, Apr. 20,
2011) (not designated for publication).
2. 	 See Tex. Health & Safety Code § 481.113(a) & (d) ("[A] person commits an offense if
the person knowingly . . . possesses with intent to deliver a controlled substance listed in Penalty
Group 2 [which offense] is a felony of the first degree if the amount of the controlled substance to
which the offense applies is, by aggregate weight, including adulterants or dilutants, four grams or
more but less than 400 grams.");  id. § 481.103(a) ("Penalty Group 2 consists of [inter alia] 3,4-methylendioxy methamphetamine").
3. 	 See Tex. Transp. Code § 547.322(d) ("A taillamp shall emit a red light plainly visible at
a distance of 1,000 feet from the rear of the vehicle.").
4. 	 Grijalva could not remember whether the appellee had two or three outstanding warrants,
and the warrants themselves were not offered into evidence.  The driver of the Mustang, Isaac
Medina (apparently the appellee's cousin), had "more than five" outstanding traffic warrants.
5. 	 The record before us contains only black and white reproductions of the photographs.
6. 	 The prosecutor cited Johnson v. State, 496 S.W.2d 72 (Tex. Crim. App. 1973), Reed v. State,
809 S.W.2d 940 (Tex. App.--Dallas 1991, no pet.), and Lewis v. State, 915 S.W.2d 51 (Tex.
App.--Dallas 1995, no pet.).
7. 	 See State v. Cullen, 195 S.W.3d 696 (Tex. Crim. App. 2006) (on request of losing party, trial
court is required to enter express findings of fact and conclusions of law).
8. 	 Those findings and conclusions were signed, however, by a different judge than the judge
who had presided over the hearing on the motion to suppress on March 19th--the record does not
reveal why.
9. 	 Tex. Code Crim. Proc. art. 44.01(a)(5).

12. 	 Id.  (quoting Reed , supra, at 948 n.3).  The court of appeals also contrasted this case to 
Fletcher v. State, 90 S.W.3d 419 (Tex. App.--Amarillo 2002, no pet.).  In Fletcher, the Amarillo
court of appeals assumed without deciding that the initial detention was illegal, but held that the taint
from any such primary illegality was dissipated by the immediate discovery of an arrest warrant.  Id.
at 420-21.  "This case differs from Fletcher[,]" the court of appeals here opined, "in that the trial
court rejected the only basis for stopping the Mustang, i.e., its allegedly defective taillights." 
Mazuca, supra, at *3.  It seems to us, however, that, whatever authoritativeness we may find
Fletcher to have, its holding with respect to attenuation of taint would not be diluted in any measure
by the fact that it assumed, without deciding, the illegality of the initial detention.
13. 	 Mazuca, supra.
14. 	 496 S.W.2d 72 (Tex. Crim. App. 1973).
15. 	 Tex. R. App. P. 66.3(a), (b) & (c).  Last year, in State v. Elias, we observed that, "[w]hile
this Court has yet to directly weigh in on this issue, we note that a number of other jurisdictions have
held that an intervening arrest warrant may, under certain circumstances, serve to attenuate taint,
depending upon an application of the attenuation factors of Brown v. Illinois[, 422 U.S. 590, 603-604
(1975)]."  339 S.W.3d 667, 678 (Tex. Crim. App. 2011).
16. 	 See Mapp v. Ohio, 367 U.S. 643, 656 (1961) ("[T]he purpose of the exclusionary rule is to
deter--to compel respect for the constitutional guaranty in the only effectively available way--by
removing the incentive to disregard it.") (internal quotation marks and citation omitted).

18. 	 371 U.S. 471, 487-88 (1963) (quoting Maguire, Evidence of Guilt, 221 (1959)).  Although
the appellee also invoked the exclusionary remedy of Article 38.23, Tex. Code Crim. Proc. art.
38.23(a), we have expressly held that the attenuation of taint doctrine also applies in determining
whether evidence has been unlawfully "obtained" for purposes of this state law provision.  Johnson
v. State, 871 S.W.2d 744, 750 (Tex. Crim. App. 1994).  Cf. Bell v. State, 724 S.W.2d 780, 787 (Tex.
Crim. App. 1986) (invoking the attenuation of taint doctrine in applying Article 38.23's exclusionary
rule with respect to violations of Texas statutory provisions).

conducted following what Johnson argued was an unconstitutional arrest did not constitute fruit of
the poisonous tree under Wong Sun in light of intervening events, namely, "he was brought before
a committing magistrate to advise him of his rights and set bail" and counsel was appointed for him;
the line-up was conducted "under the authority of the commitment" and not by exploitation of the
initial arrest).

U.S. 687, 691-93 (1982) (confession was the fruit of Taylor's illegal arrest even though it did not
take place until six hours after the arrest, where he remained in police custody, unrepresented and
under interrogation; moreover, that an arrest warrant was obtained after the illegal arrest could not
serve as an intervening circumstance adequate to attenuate taint where the evidence used to establish
probable cause for the warrant was itself a fruit of the primary illegality).

45. 	 Elias, supra, at 678 n.35.  We agree with the State that, when the primary illegality does not
generate a statement or confession, the remaining Brown factor, viz., whether the subject was given
his Miranda warnings, and if so, when, has no logical application.  State's Brief at 22.
46. 	 See People v. Hillyard, 589 P.2d 939, 941 (Colo. 1979) (en banc) (citing Brown but, in
context of the suppression of contraband, applying only "degree of police misconduct and any
relevant intervening circumstances");  United States v. Green, 111 F.3d 515, 521 (7th Cir. 1997)

suppression, is not dispositive);  State v. Hill, 725 So. 2d 1282, 1284 (La. 1998) (same);  United
States v. Johnson, 383 F.3d 538, 544-45 & n.7 (7th Cir. 2004) (applying the three Brown factors but
noting that "when a lawful arrest due to an outstanding warrant is the intervening circumstance, the
temporal component is less relevant than in situations where the police exploit an illegal detention
to create a predictable response (e.g., confession or consent to search)");  State v. Martin, 179 P.3d
457, 463 (Kan. 2008) (applying the Brown factors but noting that temporal proximity, while "it
weights heavily against the State[,]" is not dispositive, given an intervening warrant and the lack of
purposeful police misconduct).

Brown factors but seemingly finding discovery of an outstanding warrant to be practically
determinative in "dissipating the taint of an unlawful seizure");  Jacobs v. State, 128 P.3d 1085, 1089

401-06 (6th Cir. 2011) (finding no attenuation of taint with respect to the introduction of physical
evidence, even though the purposefulness-and-flagrancy factor did "not weigh heavily in the
attenuation determination[,]" because the discovery of arrest warrant in between the illegal stop and
the seizure of that evidence "resulted from means that are indistinguishable from the illegal stop, and
thus the warrant does not dissipate the taint of the unlawful detention in this case").

63. 	 Thus, we reject the State's argument that the first Brown factor should "only apply to the
taking of a confession or statement after the initial illegal arrest, not the discovery of physical
evidence as in this case."  State's Brief at 22.  Indeed, in a given fact scenario, it will often be the
case that temporal proximity will prove the determinative factor in whether the exclusionary rule
should apply.  In the instant case, for example, had Officer Grijalva not discovered an outstanding
warrant for the appellee's arrest, the brief period of time from the illegal stop to the disclosure of
contraband would counsel compellingly in favor of suppression even in the absence of any particular
purposefulness or flagrancy in the perpetration of the illegal stop.  
64. 	 We do not mean to imply that Johnson was wrongly decided on its facts.  The challenged
evidence in Johnson, the photographs from which he was identified, were not taken immediately
following Johnson's illegal detention and were preceded by the discovery of outstanding warrants
for his arrest.  There is no mention in our opinion of purposefulness or flagrancy in the detaining
officer's conduct that would operate to prevent the discovery of the outstanding warrants from
breaking the causal connection between the illegal stop and the taking of the photographs.  Thus, we
have no reason now to question our ultimate conclusion in Johnson that the evidence "would have
been obtained regardless by means sufficiently distinguishable from the underlying illegality to be
purged of the primary taint."  496 S.W.2d at 74. 
65. 	 See Cullen, supra, at 699 ("Effective from the date of this opinion, the requirement is: upon
the request of the losing party on a motion to suppress evidence, the trial court shall state its essential
findings.  By 'essential findings,' we mean that the trial court must make findings of fact and
conclusions of law adequate to provide an appellate court with a basis upon which to review the trial
court's application of the law to the facts.").
66. 	 See Elias, supra, at 673 (quoting State v. Ross, 32 S.W.3d 853, 856 (Tex. Crim. App. 2000),
which in turn quotes Guzman v. State, 955 S.W.2d 85, 89 (Tex. Crim. App. 1997)) (reviewing court
defers "to a trial court's determination of the historical facts that the record supports especially when
the trial court's fact findings are based on an evaluation of credibility and demeanor").
67. 	See id. ("The appellate court should afford the same amount of deference to trial courts'
rulings on 'application of law to fact questions,' also known as 'mixed questions of law and fact,'
if the resolution of those ultimate questions turns on an evaluation of credibility and demeanor.").
68. 	 State v. Sheppard, 271 S.W.3d 281, 291 (Tex. Crim. App. 2008);  see also id. ("[F]actual
findings are who did what, when, where, how, or why.  They also include credibility determinations. 
They do not include legal rulings on 'reasonable suspicion' or 'probable cause'; those are legal
conclusions subject to de novo review, not deference.").
69. 	 The trial court considered Grijalva's failure to give the appellee Miranda warnings before
discovering the ecstasy as a factor favoring suppression.  The appellee now argues that this was a
legitimate consideration because the appellee admitted having the ecstasy in his pocket before
Grijalva actually conducted the pat-down search that secured it, and this admission came as a direct
result of Grijalva's custodial query.  Thus, the appellee's admission was part of the chain of
causation that extended from the illegal stop to the ultimate seizure of the evidence used against him. 
Appellee's Brief at 13-15.  But the appellee does not here challenge the admissibility of his
admission itself--only of the ecstasy--and it is quite evident from Grijalva's testimony that he
would have discovered the ecstasy in any event as part of his search of the appellee's person incident
to his arrest under the outstanding warrants.  Under these circumstances, we do not consider the lack
of Miranda warnings to be a factor of any substantial weight at all.
70. 									 In Elias, we held that it would be contingently appropriate for the court of appeals to remand
the cause to the trial court, under Rule 44.4 of the Rules of Appellate Procedure, so that the trial
court could make more explicit findings with respect to a particular issue that had been expressly
litigated at the hearing on the motion to suppress.  339 S.W.3d at 676-77 & 679 (citing Tex. R. App.
P. 44.4).  We see no occasion likewise to remand the instant case.  In Elias, the arresting officer
testified that he had observed Elias fail to signal a turn within a hundred feet of an intersection, but
the trial court failed to make a specific finding with respect to the credibility of that potentially
dispositive testimony.  Id.  Here, there was little testimony at the suppression hearing specifically
pertaining to the attenuation of taint factors, and none that seems particularly to have called for the
trial court to evaluate witness credibility and demeanor.  Nor did either party seek to reopen the
suppression hearing to supplement the record with additional evidence respecting attenuation of
taint.  See Black v. State, 362 S.W.3d 626, 633-35 (Tex. Crim. App. 2012) (trial court has discretion
to reopen hearing on motion to suppress evidence and may revisit its previous ruling in light of
supplemental evidence presented therein).  Consequently, we see nothing to be gained from a remand
under Rule 44.4 to assure "the proper presentation of" the case on appeal.
71. 	 The appellee argues that for Grijalva and Chavez to have initiated the traffic stop on the
basis of defective taillights was itself such a blatant illegality as to constitute some evidence of both
purposefulness and flagrancy on their part.  Appellee's Brief at 19-22.  He relies upon United States
v. Lopez-Valdez, in which the Fifth Circuit acknowledged that, under Texas law, "state police
officers do not have authority to stop vehicles with cracked taillight lenses that 'permit[ ] some white
light to be emitted with red light.'"  178 F.3d 282, 288 (5th Cir. 1999) (quoting Vicknair v. State, 751
S.W.2d 180, 187 (Tex. Crim. App. 1987).   Moreover, the Fifth Circuit held that a traffic stop on this
basis is so obviously unlawful that the Government could not invoke the good faith exception of the
exclusionary rule to admit the fruit of the search following the unlawful stop because "no well-trained Texas police officer could reasonably believe that white light appearing with red light
through a cracked red taillight lens constituted a violation of traffic law[,]" and "if officers are
allowed to stop vehicles based upon their subjective belief that traffic laws have been violated even
where no such violation has, in fact, occurred, the potential for abuse of traffic infractions as pretext
for effecting stops seems boundless and the costs to privacy rights excessive."  Id. at 289.

	It is true that the trial court in this case expressly found that the officers "did not have a
reasonable belief that the yellow Mustang had white lights to the rear" and that the "Mustang's tail
lights emitted red light" at the time of the stop.  Findings of Fact 3 & 7, respectively.  But the trial
court made no express finding of fact with respect to whether the taillights may have emitted some 
white light and some red light.  In his redirect testimony, Grijalva seems to have acknowledged that
the taillights may have been a mixture of red and white light, although he continued to maintain that
"the white dominated the red color."  We note that the trial court concluded only that the conduct
of the officers was "flagrant"--not, specifically, that it was also purposeful.  Conclusion of Law  3. 
While Lopez-Valdez makes it evident that Grijalva and Chavez should have known better than to
conduct a traffic stop for the reason they did, nothing in the present record establishes that they
actually did know.  This may explain why the trial court failed to conclude that their conduct was
purposeful, i.e., a mere pretext for a fishing expedition.  After all, why would a police officer with
an ulterior motive, hoping that subsequent events will uncover reasonable grounds to conduct a
search, deliberately choose what he knows does not constitute a genuine traffic violation as the
purportedly objective basis for making the initial stop?  As for the trial court's conclusion that the
officers' conduct was flagrant, for reasons expressed in the text, post, we do not think the record
fairly supports this conclusion.  Even "granting the establishment of the primary illegality," Wong
Sun, supra, at 488, the conduct of the officers was not at any time egregiously abusive.  While "[t]he
impropriety of the [stop] was obvious" in light of Lopez-Valdez, Grijalva did not exhibit any
"awareness of that fact[,]" and the manner in which the stop was perpetrated does not "give[ ] the
appearance of having been calculated to cause surprise, fright, [or] confusion."  Brown, supra, at
605.
72. 	 In its Finding of Fact 17, the trial court found that the appellee "did not volunteer any
information but rather answered the officers [sic] questions when he provided his identifying
information."  But this does not mean that the appellee did not readily (if silently) comply with
Grijalva's request for identification, and there was nothing improper about Grijalva's request.  With
respect to the driver of an automobile stopped for a traffic infraction, "an officer may demand
identification[.]"  Davis v. State, 947 S.W.2d 240, 245 n.6 (Tex. Crim. App. 1997).  Even if a
detaining officer may not similarly "demand" identification from a passenger, that is not what the
evidence indisputably shows that Grijalva did in this case.  See St. George v. State, 237 S.W.3d 720,
722 (Tex. Crim. App. 2007) ("[W]hile officers may question a passenger and request identification
without separate reasonable suspicion of the passenger, they may not compel the passenger to answer
or imply that compliance with the request is required.").
