        JON P. McCALLA, District Judge. Akeem Stafford appeals his conviction and
sentence for one count of violating 18 U.S.C. § 922(g)(1), felon in possession of a
firearm and ammunition. The district court sentenced Stafford to 262 months of
imprisonment (21 years and 10 months) and five years of supervised release, after

of Tennessee, sitting by designation.

No. 12-3238        United States v. Stafford                                       Page 2


enhancing his guideline calculation based on (1) Stafford’s armed- career-criminal
status; (2) the fact that the firearm was stolen; (3) Stafford’s possessing a firearm in
relation to a felony offense; and (4) Stafford’s reckless endangerment during flight from
law enforcement.

       Stafford argues the conviction was in error because the evidence does not support
the verdict and because the district court improperly admitted gunshot-residue evidence
and related expert testimony. Stafford also argues the sentence was in error because the
district court improperly applied the Armed Career Criminal Act enhancement, relied
on impermissible documents—a state-court Bill of Particulars—to determine that his
previous conviction was a “violent felony” under the Armed Career Criminal Act, and
imposed a procedurally unreasonable sentence. Additionally, Stafford claims the
“residual clause” of the Armed Career Criminal Act is unconstitutionally vague.

       The Government concedes that the district court erred in considering the state-
court Bill of Particulars as part of its determination that Stafford’s previous conviction
for “aggravated riot” was a “violent felony” under the Armed Career Criminal Act.

       For the reasons set forth below, Stafford’s conviction is AFFIRMED. The
evidence supports the jury’s verdict and the district court did not err in allowing
gunshot-residue evidence or the related expert testimony. Stafford’s sentence is also
AFFIRMED. The district court properly applied the enhancement under the Armed
Career Criminal Act and the enhancements under the Sentencing Guidelines; the
sentence was procedurally reasonable; and the “residual clause” of the Armed Career
Criminal Act is not void for vagueness.

                                 I. BACKGROUND

       At approximately 2:00 a.m. on November 21, 2010, Defendant-Appellant Akeem
Stafford (“Stafford”) was standing outside Uncle Vic’s nightclub on Kerstetter Way in
Elyria, Ohio. As City of Elyria Police Officer Joe Figula (“Figula”) was patrolling the
area around Uncle Vic’s on Broad Street in his car, he heard a gunshot. After stopping
near the intersection of Kerstetter Way and Broad Street, Figula observed a man,
No. 12-3238            United States v. Stafford                                                    Page 3


wearing jeans and a dark zip-up sweatshirt with white lettering on the back, fire two
more gunshots. One of these rounds was later found to have struck the passenger
window of a bystander’s automobile. The shooter was later identified as Akeem
Stafford. Figula reported the shooting over his police radio, mobilizing the Elyria Police
Department to the area. Stafford looked up the hill at Kerstetter Way and saw Figula’s
police car, and Figula observed Stafford run down an adjacent alley, Tremont Street.
Figula then turned his car around and proceeded to a nearby McDonald’s parking lot
where the alley ended and where he expected Stafford to emerge.

         Stafford emerged from the alley and cut across the McDonald’s parking lot,
running past Figula’s car and into traffic. Figula observed that the suspect running from
the alley was wearing the same clothing as the shooter. As Figula attempted to follow
Stafford in his car, Stafford looked back and made visual contact with Figula by looking
“right at” him. Figula lost sight of Stafford when Stafford ran across the street and under
an overhang near the First Merit Bank building.

         Figula then drove to the east side of the First Merit Bank building, looking for
Stafford to emerge, but instead found a black SUV with passengers who advised Figula
they thought someone was shooting at them. Figula then told other officers in pursuit
of the suspect where he had last seen Stafford and returned to that location. Now on
foot, Figula searched the area around the bank building and found Stafford lying face
down, wedged between the back of the building and a large green exterior power unit.1
Figula alerted the other officers that had arrived on the scene and proceeded toward
Stafford. With his gun drawn, Figula ordered Stafford to show his hands and to come
out from his hiding place. When Stafford failed to comply, Figula jumped on Stafford’s
back, holding him down to prevent him from escaping or reaching for a firearm. Once
secured, the other officers helped Figula remove Stafford, now struggling with the
officers, from the area.



         1
           In his testimony, Figula erroneously described the building’s exterior power unit as a “large air-
conditioning power unit.” The Presentence Investigation Report, however, determined that this unit was
a “large green exterior power box.”
No. 12-3238        United States v. Stafford                                     Page 4


       After removing Stafford from between the wall and the power unit, the officers
noted that Stafford was not carrying a firearm. Figula organized a search for the
weapon, retracing Stafford’s movements backwards from behind First Merit Bank to the
Tremont Street alley near Uncle Vic’s nightclub. After the initial walkthrough yielded
no results, Figula continued down the alley back towards Kerstetter Way and Uncle
Vic’s nightclub. Figula found two spent .45-caliber shell casings on the ground near the
entrance of the alley from Kerstetter Way. On the arrival of the evidence technicians,
a third shell casing was recovered and the search for the missing firearm resumed. The
firearm, a .45-caliber semiautomatic handgun, was eventually recovered from under a
staircase in the Tremont Street alley behind Moss’ Steakhouse. Figula noted that the
gun’s magazine was partially ejected and a live round was visible in its barrel. A total
of six live rounds of ammunition were recovered from the gun. Figula also noted that
the gun was scuffed, indicating the gun may have been thrown and struck the cinder-
block wall adjacent to where the gun was found.

       Subsequent ballistics tests established that the two shell casings Figula found
were fired from the recovered firearm.         The bullet that pierced the bystander’s
automobile’s passenger window was also found to have been fired from the same
firearm.

       Stafford was arrested at the scene, handcuffed, placed in the back of a police
cruiser, and taken to the Elyria Police Department. At the precinct, Stafford’s hands
were swabbed for the presence of gunshot residue. Subsequent laboratory testing
determined the presence of the elements of gunshot residue on Stafford’s left hand.

       By indictment filed on Febraury 2, 2011, Stafford was charged with violating
18 U.S.C. § 922(g)(1), felon in possession of a firearm and six rounds of ammunition.
At arraignment, Stafford entered a plea of “not guilty.”

       Before trial, Stafford filed a motion in limine to exclude the results of the
gunshot-residue analysis and testimony relating to the analysis, pursuant to Federal
Rules of Evidence 702 and 403. Stafford also requested a Daubert hearing on the
matter. This motion was denied at the final pre-trial conference of August 11, 2011. On
No. 12-3238           United States v. Stafford                                     Page 5


August 10, 2011, the Government filed a motion in limine to exclude the testimony of
defense expert Robert Cilwa. This motion was held in abeyance at the final pre-trial
conference.

       Before trial began, the district court heard testimony and argument on the
Government’s motion in limine. The district court initially stated that both parties would
be prohibited from admitting any gunshot-residue evidence, conditioned on the defense
refraining from attempting to impeach Officer Figula’s testimony at trial. Because
defense counsel stated that he would attempt to impeach Figula’s eyewitness testimony,
and because the Government stated it would have its expert testify, the district court
concluded that both the Government’s and Stafford’s gunshot-residue experts would be
allowed to testify.

       Stafford’s jury trial began on August 22, 2011, and concluded on August 24,
2011. At trial, Figula testified for the Government regarding the events of November
21, 2010, and positively identified Stafford as the shooter. Officer Richard Buckway
recounted Stafford’s struggle with the officers and the collection of the firearm and spent
shells. Sergeant Richard Ellis testified regarding his role in the investigation, namely
performing the gunshot-residue test and collecting the gunshot-residue samples from
Stafford’s hands. The Government also introduced testimony from Martin Lewis, an
expert on gunshot residue. Lewis explained the process of a gunshot-residue test, how
the analysis of Stafford’s test was conducted, and the conclusions he drew from the test.
Joshua Barr, a forensic scientist in the firearms section of the Ohio Bureau of
Investigation, testified regarding the ballistics findings and matching the spent shells to
the recovered firearm. Thomas Hopkins, Special Agent for the Bureau of Alcohol,
Tobacco, and Firearms, testified regarding the recovered firearm’s nexus with interstate
commerce. At the close of the Government’s case, Stafford moved for acquittal pursuant
to Federal Rule of Criminal Procedure 29, which the district court denied.

       The defense introduced testimony from Stephen Gambetta, an investigator with
the Federal Defenders’ Office, relating to the distances from which Officer Figula
testified he had seen Stafford during the shooting and the subsequent pursuit. Bruce
No. 12-3238          United States v. Stafford                                       Page 6


Freeman, the bystander whose passenger window was shattered during the shooting, also
testified for the defense regarding the timing of the gunshots and when he first saw a
police car on the scene. The defense did not call its gunshot-residue expert, Robert
Cilwa. At the close of the defense’s case, Stafford again moved for acquittal, which the
district court again denied.

       The jury convicted Stafford of violating 18 U.S.C. § 922(g)(1), felon in
possession of a firearm and ammunition.

       On September 20, 2011, Stafford filed a Motion for New Trial pursuant to
Federal Rule of Criminal Procedure 33, arguing that the district court erred in admitting
the gunshot-residue evidence and the related expert testimony. The district court denied
the motion on October 19, 2011.

       The Presentence Investigation Report (“PSR”), filed on January 4, 2012,
recommended      a    base     offense   level   of   24   for   Stafford’s   violation   of
18 U.S.C. § 924(g)(1), as he had at least two prior felony convictions for crimes of
violence; a two-level enhancement under United States Sentencing Guideline
(“Guideline”) § 2K2.1(b)(4)(A) for a stolen firearm; a four-level enhancement under
Guideline § 2K2.1(b)(6) for possession of a firearm in relation to a felony offense; and
a two-level enhancement under Guideline § 3C1.2 for reckless endangerment during
flight from law enforcement.         With a calculated offense level of 32, the PSR
recommended a two-level enhancement for Stafford’s four prior convictions for crimes
of violence, which qualified Stafford as an “armed career criminal” under the Armed
Career Criminal Act (“ACCA”), 18 U.S.C. § 924(e) and Guideline § 4B1.4. According
to the PSR, Stafford’s recommended offense level was 34, with a recommended sentence
of 262 to 327 months.

       Stafford was sentenced on February 13, 2012. At the sentencing hearing,
Stafford objected to the Government’s calculated advisory Guidelines range, specifically
objecting to the four-level enhancement under Guideline § 2K2.1(b)(6)(B) for possession
of a firearm in relation to a felony offense, and the two-level enhancement under
No. 12-3238           United States v. Stafford                                               Page 7


Guideline § 3C1.2 for reckless endangerment during flight from law enforcement.2 The
district court overruled both objections and applied the enhancements.

        Stafford also objected to the enhancement under the ACCA, arguing that two of
his prior Ohio felony convictions for “aggravated riot” did not qualify as “violent
offenses.” Stafford argued that it was improper for the district court to rely on
documents other than the criminal indictment or judgment, specifically the state-court
Bill of Particulars that accompanied the “aggravated-riot” convictions, to determine
whether the felony was a “violent offense.” The district court disagreed and found that
Stafford was an armed career criminal and applied the enhancements, adopting the
guideline-range sentence of 262 to 327 months. Stafford received a sentence of
262 months of imprisonment and five years of supervised release.

         Stafford timely appealed.

                                         II. ANALYSIS

        Stafford raises two challenges to his conviction: (1) the evidence did not support
the jury’s verdict; and (2) the district court erred in admitting gunshot-residue evidence
and related expert testimony.

        Stafford raises three challenges to the sentencing proceedings in the district
court: (1) the district court improperly applied the enhancements of the ACCA; (2) the
district court announced a procedurally unreasonable sentence; and (3) the “residual
clause” of the ACCA is unconstitutionally vague.

        A.       Stafford’s Challenges to the Conviction

                 1.       Sufficiency of the Evidence

        The court reviews de novo a district court’s denial of a motion for acquittal
pursuant to Federal Rule of Criminal Procedure 29, but that decision will be affirmed “if


        2
          Stafford’s counsel referred to the two-level enhancement under Guideline § 3C1.2 as
“obstruction of justice.” The title of the guideline is “Reckless Endangerment During Fight.” U.S.S.G.
§ 3C1.2.
No. 12-3238         United States v. Stafford                                         Page 8


the evidence, viewed in the light most favorable to the government, would allow a
rational trier of fact to find the defendant guilty beyond a reasonable doubt.” United
States v. Ramirez, 635 F.3d 249, 255 (6th Cir. 2011) (quoting United States v. Solorio,
337 F.3d 580, 588 (6th Cir. 2003)) (internal quotation marks omitted); see Jackson v.
Virginia, 443 U.S. 307, 319 (1979). A court will reverse a judgment due to insufficient
evidence “only if [the] judgment is not supported by substantial and competent evidence
upon the record as a whole.” United States v. Barnett, 398 F.3d 516, 522 (6th Cir. 2005)
(alteration in original) (quoting United States v. Stone, 748 F.2d 361, 363 (6th Cir.
1984)) (internal quotation marks omitted).

        To convict a defendant of violating 18 U.S.C. § 922(g)(1), a jury must find that
the defendant “had a previous felony conviction, that the defendant knowingly possessed
the firearm specified in the indictment, and that the firearm traveled in or affected
interstate commerce.” United States v. Morrison, 594 F.3d 543, 544 (6th Cir. 2010)
(quoting United States v. Grubbs, 506 F.3d 434, 439 (6th Cir. 2007)) (internal quotation
marks omitted). Stafford challenges only the sufficiency of the evidence supporting the
conclusion that he possessed the firearm.

        Stafford argues that the evidence is insufficient because the Government’s case
hinges on one eyewitness, Officer Figula, whose testimony was “inconsistent.” Stafford
cites six specific instances of Figula’s inconsistencies: (1) Figula initially testified that
he saw the shooter “at the bottom of the hill” on Kerstetter Way, which measured
between 193 and 223 feet away, but then subsequently testified that the shooter was
“further up from the bottom of the hill” and only “170 feet” away; (2) Figula testified
that he saw the shooter as the last two shots were fired, yet Figula failed to give any
description of the shooter when he made the first “shots fired” call and did not give a
description of Stafford until Stafford had emerged from the Tremont Street alley into the
McDonald’s parking lot and was running past Figula’s car; (3) Figula initially stated in
his report that he saw Stafford shooting “directly east” towards Uncle Vic’s nightclub,
but at trial he testified that Stafford was aiming “in a southeasterly direction towards the
corner of Kerstetter [Way] and Broad Street”; (4) Figula testified that, when he heard the
No. 12-3238        United States v. Stafford                                        Page 9


shots, his police cruiser was “at the top of the hill” on Broad Street approaching the
intersection of Kerstetter Way and that he had “a clear view down the sidewalk on what
would be the west side of Kerstetter Way,” but defense witness Bruce Freeman testified
that after he left the area of Uncle Vic’s and traveled toward the intersection of Broad
Street and Kerstetter Way, he did not see a police car in the area when he heard the
gunshots and his window was struck by a bullet; (5) Figula admitted that he stated in his
report that Kerstetter Way was “choked with pedestrians and vehicle traffic” such that
he was “prevent[ed] . . . from driving the marked patrol vehicle towards Stafford,” yet
he testified that he had a clear view of the shooter and there was “no one” obstructing
his view; and (6) Figula testified that he lost sight of the suspected shooter for
approximately thirty seconds between the time the suspect ran from the scene of the
shooting and when he emerged from the alley into the McDonald’s parking lot.

       Reviewing the evidence in the light most favorable to the Government, a
reasonable jury could find Stafford guilty beyond a reasonable doubt. The court “neither
independently weighs the evidence, nor judges the credibility of witnesses who testified
at trial.” Ramirez, 635 F.3d at 255 (quoting United States v. Talley, 164 F.3d 989, 996
(6th Cir.1999)) (internal quotation marks omitted).       The appellate court “cannot
substitute its judgment for that of the jury.” Id. at 255–56.

       Stafford’s arguments regarding the inconsistencies in Figula’s testimony go
primarily to the credibility of the Government’s witness. While the jury heard the
inconsistencies in Figula’s testimony, it also heard substantial direct evidence on which
it could rely to convict Stafford.   Figula testified that he “had a clear view of the
shooter.” Figula described the shooter’s clothing:

       The shooter was wearing a black like zipup sweat shirt that had black and
       white stiped [sic] collar that would zip up [and] kind of cover the neck
       area. As the shooter turned, I was able to see cursive writing, a white
       print covering the entire back of the sweat shirt and I believe jean-style
       pants.

Figula described seeing the muzzle flashes that accompanied the final two gunshots.
Figula stated he had “observed the shooter turn and run north from where he had been
No. 12-3238        United States v. Stafford                                       Page 10


standing,” and that he “observed the shooter run down, turn and run—[into] an alleyway
here known as Tremont Street—turn down that alleyway and continue[] running away
from me.” Figula described seeing Stafford emerge from the alleyway:

       I observed the same person that was shooting the weapon off here
       emerge out of the alleyway this way, running westbound, running from
       the exit or entrance of the alleyway. . . . I observed the same person as far
       as the same clothing and same appearance as I saw the person shooting
       the weapon. . . . He looked right at me . . . .

Figula also testified about finding the firearm and the spent shells. Having heard both
the eyewitness testimony and its inconsistencies, the jury could have found Figula
credible.

       As for Stafford’s argument that Figula’s identification is questionable because
he did not describe Stafford as the shooter over the radio until after he saw Stafford
emerge from the alley, Figula explained that the reason he did not describe Stafford in
the first instance was that his “main concern . . . was getting officers heading in [his]
direction.” He continued, “The reason I didn’t give the description until a few seconds
later is because I just didn’t have the opportunity in between turning around, entering the
parking lot, and then all of a sudden [Stafford showing up] in front of me.” The jury
presumably considered both the defense’s argument and Figula’s explanation in its
deliberations. It is not unreasonable for a rational juror to credit Figula’s explanation.

       The jury was also presented photographic evidence of Stafford wearing the jacket
Figula identified. Figula testified that the Government’s photograph depicted Stafford
as he was taken into custody near First Merit Bank, and that Stafford was wearing “the
same jacket that [Figula] had seen the shooter wearing.” Figula described the jacket in
the photograph for the jury: “It is a black and colored sweatshirt style zipup and has the
white writing across the back with the cursive that was able to stick out in my mind as
[Stafford] turned to flee away from me on foot.”

       Stafford also questions Figula’s seemingly inconsistent testimony that Kerstetter
Way was both “choked with pedestrians and vehicle traffic” and yet he had a clear view
No. 12-3238         United States v. Stafford                                      Page 11


of the shooter firing his weapon. Review of the testimony indicates, however, that
Figula stated that while pedestrians were fleeing the scene and running up the hill, there
were no pedestrians on the same side of the street as Stafford at the time of the shooting.
Figula stated that “there was nobody other than the one person that I observed shooting
the gun . . . on this side of the road. . . . I had a clear view of the shooter.” A rational
juror could find Figula’s testimony on this issue credible.

        As for Freeman’s testimony that he did not see any police cars at the intersection
of Kerstetter Way and Broad Street at the time of the shooting, Freeman also stated on
direct examination that he “was not paying enough attention with everything going on
outside the car to really notice a police cruiser.” The jury heard sufficient testimony to
assess Freeman’s credibility in relation to Figula’s version of the events. Moreover, the
jury could reconcile the testimony of Freeman and Figula.

        Regarding the circumstantial evidence of Stafford’s guilt, “[c]ircumstantial
evidence alone can sustain a guilty verdict and . . . [such] evidence need not remove
every reasonable hypothesis except that of guilt.” Ramirez, 635 F.3d at 256 (alterations
in original) (quoting United States v. Stone, 748 F.2d 361, 362 (6th Cir. 1984)) (internal
quotation marks omitted). “Actual or constructive possession is sufficient to give rise
to criminal liability under § 922(g). Both actual and constructive possession may be
proved by circumstantial evidence.” United States v. Castano, 543 F.3d 826, 837 (6th
Cir. 2008) (quoting United States v. DeJohn, 368 F.3d 533, 545 (6th Cir. 2004)) (internal
quotation marks omitted).

        The jury heard testimony linking the shell casings and bullet recovered at the
scene to the firearm found in the Tremont Street alley. Joshua Barr testified as a
ballistics expert for the Government. Barr compared the shell casings found at the scene
with shell casings he test-fired from the recovered firearm. Barr concluded that
“[m]icroscopic comparisons” of the recovered shell casings with the test-fired shell
casings revealed that the recovered shell casings had been fired from the recovered
firearm. Barr also compared a bullet recovered at the scene with a test-fired bullet and
testified that the recovered bullet had “matching individual detail with the test-fired
No. 12-3238          United States v. Stafford                                   Page 12


bullets.” Barr concluded that the bullet recovered at the scene was fired from the
recovered firearm.

       The jury heard testimony that the shooter was wearing a black zip-up sweatshirt
with white writing, that the shooter ran down the Tremont Street alley after seeing
Figula’s police car, that Stafford was wearing the same clothing when he emerged from
the alleyway and ran past Figula’s car, that Stafford continued running and hid behind
the back of the First Merit Bank building, that Stafford wedged himself between the
building and an electrical power box, that Stafford refused to surrender or show his
hands to police when he was found, that Stafford continued to struggle with police as
they arrested him, and that a scuffed firearm with a partially ejected magazine was found
in the Tremont Street alley that matched the spent shells found near the scene of the
shooting. The jury could therefore rationally infer that Stafford threw the gun into the
alley as he was running from police. Additionally, Stafford’s actions raise an inference
of guilt: he continued to run from police and refused to cooperate when asked to show
his hands and to come out of hiding. Although circumstantial, the evidence is sufficient
for a juror to infer that Stafford was the shooter.

       Viewing the evidence in the light most favorable to the Government, a rational
trier of fact could find Stafford guilty beyond a reasonable doubt. Therefore, Stafford’s
conviction is affirmed.

               2.       Gunshot-Residue Evidence and Expert Testimony

       The court reviews a district court’s evidentiary rulings under an abuse-of-
discretion standard. United States v. Ashraf, 628 F.3d 813, 826 (6th Cir. 2011).
“District courts have broad latitude in deciding whether to admit expert testimony under
Daubert v. Merrell Dow Pharmaceuticals, Inc., 509 U.S. 579 (1993). Such decisions
are similarly reviewed under the abuse-of-discretion standard.” Id. (citations omitted).

       Stafford argues that the district court abused its discretion in admitting the
gunshot-residue evidence and the related expert testimony because they both fail to meet
the standards of Daubert and Federal Rule of Evidence 702. Stafford made similar
No. 12-3238        United States v. Stafford                                      Page 13


arguments before trial as to the admissibility of the gunshot-residue evidence and the
experts’ testimony, but the district court concluded that both were admissible because
Stafford’s “arguments [went] to the weight, not the admissibility,” of the evidence and
testimony.

       Stafford makes four arguments regarding the inadmissibility of the gunshot-
residue evidence. First, Stafford states that “[gunshot-residue] testing will not determine
whether an individual fired a gun, was present when a gun was fired by someone else,
or was merely in an environment in which [gunshot residue] existed.” Stafford claims
that because these three possible outcomes summarize the testimony of the
Government’s expert Robert Lewis—and because Lewis could not testify whether
Stafford actually fired the weapon—Lewis “could not reasonably make any conclusions
as to the actual source of the six [gunshot-residue] particles found,” and therefore
Lewis’s testimony did not meet the standards of Daubert or Rule 702.

       Under Rule 702, an expert may offer scientific or technical testimony if the court
finds the witness is qualified by “‘knowledge, skill, experience, training, or education’”;
that the testimony is relevant; and that the testimony is reliable. In re Scrap Metal
Antitrust Litig., 527 F.3d 517, 528–29 (6th Cir. 2008) (quoting Fed. R. Evid. 702).
Stafford, in claiming that the expert’s conclusion is inadmissible, is challenging the
expert’s reliability, not his qualifications or the testimony’s relevance. To determine the
testimony’s reliability, the court does not “determine whether [the opinion] is correct,
but rather [determines] whether it rests upon a reliable foundation.” Id. at 529–30. As
gatekeeper, the trial court only determines the admissibility of expert evidence; the jury
determines its weight. The court’s focus is “solely on principles and methodology, not
on the conclusions that they generate.” Daubert, 509 U.S. at 595.

       The district court was clear when it admitted the expert testimony relating to the
gunshot residue test: “Whether the jury will put any weight on either [expert], I don’t
know, but [the Defendant’s] arguments go to the weight [of the evidence], not the
admissibility.” The district court stated that allowing the expert to testify would allow
vigorous cross-examination of the expert’s “vague conclusions” and the jury would then
No. 12-3238         United States v. Stafford                                        Page 14


decide. See Daubert, 509 U.S. at 596 (“Vigorous cross-examination . . . [is a] traditional
and appropriate means of attacking shaky but admissible evidence.”). In revisiting the
issue on the second day of trial, the district court stated:

        I am allowing the government to put [the expert’s testimony] in. But
        given that your own expert is going to say it is possible that he has got
        those two traces either because he was right near a shooter, [was] a
        shooter of a gun[,] or that he came into contact with residue, I am
        permitting the defense to point that out. The two go together.

Therefore, the district court did not abuse its discretion in admitting the expert testimony
of Robert Lewis relating to the results of the gunshot-residue test.

        Second, Stafford argues that gunshot-residue testing is imprecise in that “[t]here
is no consensus in the discipline as to how many particles . . . must be identified in order
to report an item of evidence as positive for [gunshot residue].” Despite this argument,
the trial record indicates that Stafford did not object to the district court’s statement that
“the Defendant is not disputing he had gunshot residue on his hands.” Additionally,
Stafford relies on a Summary of the FBI Laboratory’s Gunshot Residue Symposium
report in both his Brief and his motion in limine filed August 8, 2011. The Summary
states that “[m]ost experts felt that even one particle is enough for a ‘positive’ result.”
As the Supreme Court noted in Daubert, “[w]idespread acceptance can be an important
factor in ruling particular evidence admissible.” Daubert, 509 U.S. at 594. At trial, the
Government’s expert testified that Stafford’s gunshot-residue test revealed five
qualifying particles present on Stafford’s left hand. The results of the test indicate that
the conclusion that Stafford had gunshot residue on his hand was reliable. The district
court did not abuse its discretion in admitting the results of the gunshot-residue test.

         Third, Stafford claims that the possibility of inadvertent transfer of gunshot-
residue particles to a suspect’s hands creates prejudice that outweighs the test’s
probative value. Stafford’s argument goes to the admissibility of circumstantial
evidence, not the admissibility of scientifically reliable evidence. The district court
found, correctly, the gunshot-residue evidence to be sufficiently reliable and allowed its
No. 12-3238         United States v. Stafford                                       Page 15


admission. The admission of such circumstantial evidence need not “remove every
hypothesis but guilt.” United States v. Ingrao, 844 F.2d 314, 315 (6th Cir. 1988).

        As to its probative value, which is discussed further infra, the evidence allowed
the jury to infer that Stafford was in possession of the firearm and to decide how much
weight to give that conclusion. The trial record also indicates that the defense cross-
examined the Government’s expert extensively on this very point—that there can be
inadvertent transfer of gunshot residue resulting in “contamination.”

        Finally, Stafford argues that the gunshot residue is inadmissible because it is
undisputed that the Elyria Police Department “fail[ed] to use proper evidence gathering
techniques in testing for [gunshot residue].” The trial record indicates that the officers,
in conducting Stafford’s arrest: did not bag his hands; could have transferred gunshot
residue to Stafford’s hands from handling their own weapons, from the backseat of the
police car, or from the booking area of the Elyria Police Department; and did not swab
Stafford’s hands until after he had been booked. These arguments, while potentially
valid as to the accuracy of the test and the conclusions to be drawn from it, do not relate
to the test’s reliability or the reliability of the expert testimony. Furthermore, Stafford’s
arguments go to the weight of the gunshot-residue evidence, not its admissibility, which
was properly considered by the jury. Again, the cross-examination of the expert at trial
allowed the jury to consider the weight of the gunshot-residue evidence and any
shortcomings in evidence collection by the Elyria Police Department. Therefore, the
district court did not abuse its discretion in admitting the evidence.

        Stafford also argues that the gunshot-residue evidence was improperly admitted
under Federal Rule of Evidence 403, as its “probative value was substantially
outweighed by a danger of unfair prejudice.” See Fed. R. Evid. 403. “Because of the
highly discretionary nature of this balancing process, the district court’s decision is
afforded great deference.” United States v. Bell, 516 F.3d 432, 445 (6th Cir. 2008). “In
reviewing the district court’s balancing of prejudice and probative value, we look at the
evidence in the light most favorable to its proponent, maximizing its probative value and
No. 12-3238         United States v. Stafford                                    Page 16


minimizing its prejudicial effect.” Id. (citation omitted) (internal quotation marks
omitted).

       Stafford contends that because a positive finding of gunshot residue on a
defendant could only reveal (1) that the individual “discharged a firearm,” (2) that the
individual “was in close proximity to a firearm when it was discharged,” or (3) that the
individual “came into contact or handled something that had gunshot residue on it,” its
probative value was “questionable” because it offered “two non-incriminating
possibilities and one incriminating possibility.” Stafford did not attempt to impeach the
conclusion that gunshot residue was found on his hands, and defense counsel thoroughly
explored the weaknesses in the gunshot-residue testing on cross-examination.

       Regarding the issue of whether the evidence was probative, the district court
stated that if the gunshot-residue evidence was being used to corroborate Figula’s
eyewitness account, “it becomes relevant because it bolsters the credibility of [the
Government’s] witness.” Viewing the admitted evidence in the light most favorable to
the Government, the gunshot-residue test corroborates Figula’s testimony that Stafford
was the shooter outside Uncle Vic’s nightclub and was not unfairly prejudicial under
Rule 403. The district court did not abuse its discretion in admitting the evidence.

       The district court’s admission of the gunshot-residue evidence and accompanying
expert testimony is, therefore, affirmed.

       B.      Stafford’s Challenges to the Sentencing

               1.       Application of the Armed Career Criminal Act

       A district court’s interpretation and application of the ACCA is a question of law,
reviewed de novo. United States v. Graves, 60 F.3d 1183, 1185 (6th Cir. 1995).
Whether a prior conviction qualifies as a “violent felony” under the ACCA is also a
question of law the court reviews de novo. United States v. Johnson, 675 F.3d 1013,
1016 (6th Cir. 2012).
No. 12-3238         United States v. Stafford                                       Page 17


        The ACCA provides a mandatory minimum fifteen-year term of imprisonment
for offenders convicted of violating 18 U.S.C. § 922(g)(1), felon in possession of a
firearm, after having sustained three qualifying prior convictions of either crimes of
violence or serious drug offenses. 18 U.S.C. § 924(e)(1). Section 924(e) defines “violent
felony” as

        any crime punishable by imprisonment for a term exceeding one year . . .
        that (i) has as an element the use, attempted use, or threatened use of
        physical force against the person of another; or (ii) is burglary, arson, or
        extortion, involves use of explosives, or otherwise involves conduct that
        presents a serious potential risk of physical injury to another . . . .

18 U.S.C. § 924(e)(2)(B).

        The district court found that Stafford qualified as an armed career criminal based
on four prior predicate offenses, including two convictions for “aggravated riot,” in
violation of Ohio Revised Code Section 2917.02(A)(2). The district court found
Stafford had an adjusted offense level of 32, criminal history category VI, resulting in
an advisory Guidelines range of 210 to 262 months of imprisonment. With the ACCA
enhancement, the district court found Stafford had a total offense level of 34, criminal
history category VI, resulting in an advisory Guidelines Range of 262 to 327 months of
imprisonment.

        Stafford argues that his “aggravated-riot” convictions do not qualify as “violent
offenses.” As the parties do not contend that the “aggravated-riot” conviction falls under
the first two types of “violent felonies” in § 924(e), it falls under the statute’s “residual
clause”: a crime that “otherwise involves conduct that presents a serious potential risk
of physical injury to another.” 18 U.S.C. § 924(e)(2)(B)(ii).

        “[I]n determining the nature of a defendant’s prior conviction, we apply a
‘categorical’ approach, meaning that we look at the statutory definition of the crime of
conviction, not the facts underlying that conviction, to determine the nature of the
crime.” United States v. Ford, 560 F.3d 420, 421–22 (6th Cir. 2009); see also Taylor
v. United States, 495 U.S. 575, 602 (1990). If the court finds that the statutory language
No. 12-3238        United States v. Stafford                                      Page 18


fails to clarify whether the underlying conviction is a crime of violence, or if “it is
possible to violate a criminal law in a way that amounts to a crime of violence and in a
way that does not,” Ford, 560 F.3d at 422, the court may consider “the statutory
definition, charging document, written plea agreement, transcript of plea colloquy, and
any explicit factual finding by the trial judge to which the defendant assented” to
determine if the underlying conviction was a crime of violence. Shepard v. United
States, 544 U.S. 13, 16 (2005); see also United States v. Jones, 673 F.3d 497, 504 n.2
(6th Cir. 2012) (calling this analysis the “modified categorical approach”).

       At Stafford’s sentencing, the district court found that

       under the categorical approach or even modified categorical approach,
       both of [the “aggravated-riot” convictions] qualify as predicate offenses
       of violence, and I further find that with respect to [Stafford’s 2005
       “aggravated-riot” conviction], that the Bill of Particulars, which was filed
       about three months before [Stafford’s] guilty plea, makes clear that this
       was a crime of violence . . . . [T]here’s no question in the Court’s mind
       that this aggravated riot was a crime of violence.

Stafford argues that the district court erred in applying the modified categorical approach
and finding that his convictions under Ohio’s “aggravated riot” statute were violent
felonies because it relied on both the PSR and the Bill of Particulars that accompanied
his 2005 “aggravated-riot” conviction, both of which are impermissible documents under
Shepard. The Government agrees that the district court erred in considering these
documents. The Government argues, however, that we should find that Stafford’s
“aggravated-riot” convictions are violent felonies based on the permissible Shepard
documents in the record.

       This court previously considered, in an unpublished opinion, the question of
whether Ohio’s “aggravated riot” offense qualifies as a “violent felony” under the
ACCA. United States v. Sanders, 301 F. App’x 503 (6th Cir. 2008) (per curiam). In
Sanders, a panel of this court determined that “aggravated riot” under the Ohio statute
included both violent and non-violent offenses. The statute provides, in relevant part:
No. 12-3238         United States v. Stafford                                    Page 19


       (A) No person shall participate with four or more others in a course of
       disorderly conduct in violation of [Ohio’s Disorderly Conduct statute]:
       (1) With purpose to commit or facilitate the commission of a felony;
       (2) With purpose to commit or facilitate the commission of any offense
       of violence;
       (3) When the offender or any participant to the knowledge of the
       offender has on or about the offender’s or participant’s person or under
       the offender’s or participant’s control, uses, or intends to use a deadly
       weapon or dangerous ordnance, as defined in section 2923.11 of the
       Revised Code.

Ohio Rev. Code Ann. § 2917.02(A). Sanders held that violation of subsection (A)(1)
was not an offense of violence, as it “lack[ed] as an element the use of force.” Sanders,
301 F. App’x at 506. Sanders then discussed the offenses in subsections (A)(2) and
(A)(3) of the statute:

       Here, subsections (A)(2) and (3) of the aggravated riot statute prohibit
       conduct that poses risk of physical injury through “offense[s] of
       violence” or use of “a deadly weapon or dangerous ordnance.” As a
       categorical matter, conduct under those subsections would obviously
       qualify as a crime of violence. However, as previously discussed, it is
       equally obvious that conduct under subsection (A)(1), does not
       necessarily pose a risk of physical injury.

Id. (alteration in original) (footnote omitted).

       Although unpublished decisions are not binding precedent on subsequent panels,
“their reasoning may be ‘instructive’ or helpful,” Crump v. Lafler, 657 F.3d 393, 405
(6th Cir. 2011), “especially where there are no published decisions which will serve as
well,” Hood v. Keller, 229 F. App’x 393, 398 n.5 (6th Cir. 2007) (internal quotation
marks omitted). In the instant case, no other Sixth Circuit case is on point. Therefore,
Sanders is instructive and we will follow its reasoning.

       Stafford argues that Sanders is inapplicable to the instant case because, in that
case, the panel found that Sanders violated subsection (A)(3) of the “aggravated-riot”
statute, not subsection (A)(2). In fact, however, Sanders did not determine which
subsection the defendant violated. The panel applied the modified categorical approach
and reviewed Sanders’s indictment, which stated that Sanders
No. 12-3238        United States v. Stafford                                      Page 20


       did participate with four (4) or more others in a course of disorderly
       conduct in violation of Section 2917.11 of the Revise[d] Code with
       purpose to commit or facilitate the commission of an offense of violence
       [and] . . . had used or intended to use a deadly weapon or dangerous
       ordnance, in violation of Section 2917.02 of the Ohio Revised Code.

Id. at 507 & n.2 (first alteration in original). The panel found that Sanders’s indictment
did not “cite to a specific subsection of section 2917.02. However, the language of the
indictment was identical to the statutory language, revealing that his prior conviction
was undoubtedly for violation of either subsection (A)(2) or (A)(3) of Ohio’s
aggravated-riot statute, both of which are crimes of violence . . . .” Sanders, 301 F.
App’x at 507 (emphasis added). Therefore, the reasoning of Sanders is instructive.

       Following the modified categorical approach and looking beyond the statutory
language of the Ohio Revised Code to the underlying Shepard documents, Stafford’s
state-court indictments specifically charged him with violating section 2917.02(A)(2).
The language of Stafford’s indictments tracks the statutory language and the language
used in the Sanders indictment. Both of Stafford’s plea agreements provided he agreed
to plead guilty to violations of section 2917.02(A)(2). The judgment states that Stafford
violated section 2917.02(A)(2). In Sanders, the panel analyzed nearly identical language
in an indictment and concluded that whether the defendant was convicted of violating
either subsection (A)(2) or (A)(3), the violation would be a “crime of violence” for
sentencing purposes. Sanders, 301 F. App’x at 507.

       Because the finding that subsection (A)(2) was categorically a violent felony
under the ACCA was not essential to the holding in Sanders, we will now separately
address that subsection.

       Stafford argues that the district court erred in classifying “aggravated riot” as a
“violent felony” under 18 U.S.C. § 924(e) because the offense “does not necessarily
involve conduct presenting a serious potential risk of physical injury to another.”
Stafford cites his state-court indictments and argues that they fail to identify what
“offense of violence” he was convicted of committing, and are therefore not sufficient
to qualify “aggravated riot” as a “violent felony” under the ACCA. Stafford argues that
No. 12-3238         United States v. Stafford                                     Page 21


the term “offense of violence,” as used in section 2917.02(A)(2), must encompass all the
“offenses of violence” enumerated in Ohio Revised Code Section 2901.01(A)(9), some
of which do not require the “offender’s use, attempted use, or threatened use of physical
force against the person of another” or “otherwise involve conduct presenting a serious
potential risk of physical injury to another.” As a result, Stafford claims the “breadth of
the offenses of violence the statute includes[] cannot reasonably be found to be roughly
similar, in kind and degree of risk posed, to the listed enumerated crimes in the
ACCA—crimes which typically involve purposeful, violent, and aggressive conduct.”

        The ACCA’s residual clause is not a catch-all provision. See United States v.
Benton, 639 F.3d 723, 731 (6th Cir. 2011).              Instead, “the provision’s listed
examples—burglary,          arson,   extortion,   or   crimes   involving   the   use   of
explosives—illustrate the kinds of crimes that fall within the statute’s scope. Their
presence indicates that the statute covers only similar crimes, rather than every crime
that ‘presents a serious potential risk of physical injury to another.’” Begay v. United
States, 553 U.S. 137, 142 (2008) (quoting 18 U.S.C. § 924(e)(2)(B)(ii)). The offenses
encompassed by § 924(e)(2)(B)(ii) are limited “to crimes that are roughly similar, in
kind as well as in degree of risk posed, to the examples themselves.” Id. at 143; see also
Johnson, 675 F.3d at 1019–20 (finding Missouri’s “third-degree felony assault” statute
to be a violent felony); United States v. Clark, 458 F. App’x 512, 515–16 (6th Cir. 2012)
(finding Kentucky’s “wanton endangerment” statute to be a violent felony); Benton,
639 F.3d at 732 (finding Tennessee’s “solicitation to commit aggravated assault” statute
to be a violent felony) .

        In Benton, the Court stated,

        [W]hether an offense involves “violent, aggressive, and purposeful”
        conduct is not the only point of comparison that we may consider when
        determining whether an offense is similar in kind and degree to the listed
        examples. . . . Instead, Begay additionally directs us to look to whether
        the offense “conduct is such that it makes more likely that an offender,
        later possessing a gun, will use that gun deliberately to harm a victim.”
No. 12-3238        United States v. Stafford                                      Page 22


Benton, 639 F.3d at 731–32 (citation omitted) (quoting Begay, 553 U.S. at 144–46). The
Sixth Circuit has interpreted the Supreme Court’s decision in Begay as creating a
two-part test: for an offense to be “considered a ‘violent felony’ under the second prong
of the ACCA,” it must “‘(1) pose[] a serious potential risk of physical injury to others;
and (2) involve[] the same kind of purposeful, violent, and aggressive conduct as the
enumerated offenses of burglary, arson, extortion, or offenses involving the use of
explosives.’” Benton, 639 F.3d at 732 (quoting United States v. Young, 580 F.3d 373,
377 (6th Cir. 2009)).

       Analyzing the “aggravated-riot” offense under the Benton test, a court first asks
if the acts “posed a serious potential risk of physical injury to others.” Ohio’s
“aggravated-riot” statute is only violated when a group of four or more people act in a
disorderly manner. Although Sanders found that there was a non-violent way of
violating subsection (A)(1) of the “aggravated-riot” statute, it recognized that “not every
hypothetical offense covered by a criminal statute need be violent in order to qualify as
a crime of violence.” Sanders, 301 F. App’x at 507 (citing James v. United States,
550 U.S. 192, 208 (2007)); see also Johnson, 675 F.3d at 1019 (finding third-degree
assault to be a violent felony despite the fact that the offense could potentially be
committed through “guile, deception, or deliberate omission”).           Also, to violate
subsection (A)(2), the group must act “with purpose” to commit an offense of violence.
The proper inquiry, then, is whether “engaging in a course of disorderly conduct with
at least four other individuals, with the specific intent to commit the offense of violence
in question,” presents a risk of physical injury to others.

       The statute itself contemplates a risk of physical injury to others; in order to
violate the statute one must have the purpose of committing an offense of violence. By
its own terms, the violation presents a risk of injury. Multiplying that by four people,
there is a “serious potential risk of physical injury to others.” See Callanan v. United
States, 364 U.S. 587, 593 (1961) (“[C]ollective criminal agreement . . . presents a greater
potential threat to the public than individual delicts.”). The “aggravated-riot” statute
requires specific intent to commit violence. Therefore, the “offenses of violence”
No. 12-3238          United States v. Stafford                                    Page 23


enumerated under section 2901.01(A)(9) that lack the adequate mens rea are excluded.
As a result, the “aggravated-riot” statute is not over-broad as Stafford suggests.

        The second inquiry under Benton, whether the offense “involves the same kind
of purposeful, violent, and aggressive conduct as the enumerated offenses of burglary,
arson, extortion, or offenses involving the use of explosives,” is also answered in the
affirmative. As stated above, violation of Ohio’s “aggravated-riot” statute involves
specific intent, just as do the offenses of burglary, arson, and extortion. There is no
question, then, that “aggravated riot” involves “purposeful conduct” commensurate with
the other offenses. When combined with Begay’s inquiry whether the “conduct is such
that it makes more likely that an offender, later possessing a gun, will use that gun
deliberately to harm a victim,” it is logical to conclude that the acts of four or more
people, engaged in a course of disorderly conduct with the purpose to commit an offense
of violence present a high risk of serious injury. Add to that the possession of a gun, and
that risk is even greater.

        Therefore, the district court’s conclusion that a violation of Ohio Revised Code
Section 2917.02(A)(2) is a “violent felony” under the ACCA and that Stafford qualified
as an armed career criminal as a result is affirmed.

                2.      Reasonableness of the Sentence

        This court reviews sentences for procedural reasonableness under an abuse-of-
discretion standard. Gall v. United States, 552 U.S. 38, 51 (2007). A sentence will be
deemed “procedurally unreasonable” when the district court sentencing the defendant
“‘fail[s] to calculate (or improperly calculat[es] ) the Guidelines range, treat[s] the
Guidelines as mandatory, fail[s] to consider the [18 U.S.C.] § 3553(a) factors, select[s]
a sentence based on clearly erroneous facts, or fail[s] to adequately explain the chosen
sentence—including an explanation for any deviation from the Guidelines range.’”
United States v. Taylor, 648 F.3d 417, 422 (6th Cir. 2011) (alterations in original)
(quoting Gall, 552 U.S. at 51).
No. 12-3238          United States v. Stafford                                     Page 24


        Stafford’s argument that his sentence was procedurally unreasonable concerns
two Guideline enhancements: possessing a firearm in connection with another felony
offense and creating a substantial risk of serious injury or death while fleeing from law
enforcement. For the reasons discussed infra, Part II.B.3, the district court did not abuse
its discretion, and Stafford’s sentence was procedurally reasonable.

                3.      Application of the Sentencing Guidelines Enhancements

        “We review de novo a district court’s application of the Sentencing Guidelines
when that application involves mixed questions of law and fact. . . . [and w]e review for
clear error a district court’s findings of fact in connection with sentencing.” United
States v. Hayes, 135 F.3d 435, 437 (6th Cir. 1998) (citation omitted). “A factual finding
is clearly erroneous when the reviewing court on the entire evidence is left with the
definite and firm conviction that a mistake has been committed.” United States v. Moon,
513 F.3d 527, 540 (6th Cir. 2008) (internal quotation marks omitted). “A district court’s
sentencing determination is reviewed ‘under a deferential abuse-of-discretion standard’
for reasonableness, which has both a procedural and a substantive component.” United
States v. Erpenbeck, 532 F.3d 423, 430 (6th Cir. 2008) (quoting Gall, 552 U.S. at 41).

                        a.      Enhancement Under Guideline § 2K2.1(b)(6)

        Guideline § 2K2.1(b)(6) applies when a defendant possesses a gun “with
knowledge, intent, or reason to believe that it would be used or possessed in connection
with another felony offense.” U.S.S.G. § 2K2.1(b)(6)(B). The Guideline’s comments
state that the subsection “appl[ies] if the firearm or ammunition facilitated, or had the
potential of facilitating, another felony offense or another offense, respectively.”
U.S.S.G. § 2K2.1 cmt. n.14(A). The court “accord[s] due deference to the district
court’s determination that [§ 2K2.1(b)(6)’s] enhancement applies.” Taylor, 648 F.3d at
431 (quoting United States v. Burke, 345 F.3d 416, 426–27 (6th Cir. 2003)) (internal
quotation marks omitted). Assessing the nexus between a firearm and a felony requires
a fact-specific inquiry, under which the court affords due deference to the district court’s
No. 12-3238        United States v. Stafford                                     Page 25


findings. Id. at 432. The district court’s factual findings are reviewed for clear error.
Id.

       Stafford argues that the district court erred in “applying the enhancement because
there was no evidence presented from which to infer any intent by Stafford to commit
another felony offense with the gun.” Stafford relies on United States v. Payne, 462 F.
App’x 579, 582 (6th Cir. 2012) (per curiam), claiming that the Government was required
to show that Stafford possessed the “firearm with the intent to possess or use it, at some
time in the future, in connection with another felony offense.”

       The comments to the Guideline, however, make it clear that the enhancement
applies to situations where the “firearm or ammunition facilitated . . . another felony
offense.” U.S.S.G. § 2K2.1 cmt. n. 14(A). By the plain language of the comments, it
is not necessary to show that, at the time Stafford possessed the gun, he also had the
intent to use it in a future felony. The district court found that Stafford possessed the
gun and that he committed another felony offense, namely, shooting into a crowd:

       [T]here was evidence that the Defendant discharged the firearm either
       toward a car or into a crowd. Although he wasn’t charged, I heard the
       evidence at the trial, and I find by a preponderance of the evidence that
       the Defendant possessed the firearm, and that he committed . . . another
       crime at the time.

Under the Guidelines, the district court’s findings are not clearly erroneous and are
affirmed.

                       b.      Enhancement Under Guideline § 3C1.2

       Guideline § 3C1.2 applies if the defendant “recklessly created a substantial risk
of death or serious bodily injury to another person in the course of fleeing from a law
enforcement officer.” U.S.S.G. § 3C1.2. “Because the ‘question of what constitutes
endangerment is a mixed question of law and fact . . . [that] is highly fact-based,’ we
give ‘significant deference to the district court.’” United States v. Dial, 524 F.3d 783,
785 (6th Cir. 2008) (alteration in original) (quoting United States v. Hazelwood, 398
F.3d 792, 796 (6th Cir. 2005)). In order to apply the § 3C1.2 enhancement, a court must
No. 12-3238          United States v. Stafford                                      Page 26


find that the defendant knew, or had reason to know, that he was fleeing from a law-
enforcement officer. Hayes, 135 F.3d at 438.

          Stafford argues that the Government failed to meet its burden. Stafford claims
that the district court failed to make a finding that Stafford knew or had reason to know
that he was fleeing from law enforcement and that the trial record does not support the
district court’s conclusion. Stafford also claims that the district court erred in concluding
that “the act of carrying a loaded gun while allegedly fleeing law enforcement recklessly
created a substantial risk of death or serious bodily injury to another person.” (emphasis
added).

          Stafford’s first claim, that the district court did not make a finding of fact that
Stafford knowingly fled from law enforcement, is not supported by the record. At the
sentencing hearing, Judge Polster stated, “I heard the trial testimony about the
Defendant’s fleeing law enforcement while in possession of a loaded firearm, and so I
find [Stafford’s objection to the enhancement is] overruled.” Furthermore, the record
supports that finding. At trial, the court heard testimony that: Officer Figula witnessed
Stafford fire the gun; Stafford looked toward the top of the hill where Figula’s car was
located before he fled into the alley; Stafford emerged from the alley without a gun;
Stafford saw the police car upon exiting the alley into the McDonald’s parking lot and
continued to run; Stafford hid himself behind the First Merit Bank building; and the
police found the loaded weapon discarded in the alley that Stafford had run through.
Under a preponderance-of-the-evidence standard, there is sufficient evidence to find that
Stafford knew he was fleeing from law enforcement. See United States v. Gates,
461 F.3d 703, 708 (6th Cir. 2006) (“[J]udicial fact-finding for sentencing purposes must
continue as it was conducted prior to Booker, under a preponderance of the evidence
standard.”); see also United States v. White, 551 F.3d 381, 384–85 (6th Cir. 2008) (en
banc). Therefore, the district court’s findings of fact are not clearly erroneous.

          As for Stafford’s second argument regarding whether his actions rose to the
required level of “recklessly” creating a substantial risk of death or serious bodily injury,
there was testimony that Stafford threw a loaded gun against a building, close to a
No. 12-3238         United States v. Stafford                                      Page 27


crowded street and nightclub. The Guidelines themselves explain that “reckless” means
“a situation in which the defendant was aware of the risk created by his conduct and the
risk was of such a nature and degree that to disregard that risk constituted a gross
deviation from the standard of care that a reasonable person would exercise in such a
situation.” U.S.S.G. § 2A1.4 cmt. n.1.

        While not binding authority, United States v. Howard, 301 F. App’x 446 (6th Cir.
2008), is instructive. In Howard, the defendant disputed his enhanced sentence under
§ 3C1.2 claiming that simply “having” a gun did not create the substantial risk necessary
under the Guideline. 301 F. App’x at 449. The court in Howard found that the
defendant did not “merely have a gun,” but instead “threw a loaded and cocked gun . .
. while fleeing” and that such action created the substantial risk. Id. In the instant case,
Stafford, too, was not simply “carrying” a gun; he was carrying a loaded gun that he then
threw behind the staircase of a business.

        Stafford attempts to distinguish his case from previous Sixth Circuit cases
upholding a § 3C2.1 enhancement by arguing that, in his case, “there was no evidence
of pedestrian traffic, or nearby schools, churches, playgrounds, or residential housing”
near the discarded firearm. See, e.g., United States v. May, 430 F. App’x 520, 525–27
(6th Cir. 2011) (upholding a § 3C2.1 enhancement where defendant discarded a loaded
gun in a housing project, where children and pedestrian traffic were common); United
States v. Allen, 51 F.3d 273 (6th Cir. 1995) (per curiam) (holding that discarding a gun
in a residential neighborhood, whether loaded or unloaded, where it could easily be
recovered was reckless endangerment). Stafford erroneously concludes that these
examples encompass the entire spectrum of locations where one would be reckless to
discard a gun. To the contrary, Stafford’s acts are a “gross deviation from the standard
of care that a reasonable person would exercise in such a situation.” Stafford threw a
loaded gun into an area in the rear of a restaurant, near where employees regularly took
the restaurant’s trash. Officer Figula testified that other pedestrians were running
through that alley shortly after the shooting. As a result, there was a significant
possibility that a bystander could have come across the loaded weapon and been hurt,
No. 12-3238          United States v. Stafford                                      Page 28


or used it to hurt someone else. These actions created a substantial risk of serious injury.
Under the Guidelines, the district court’s findings are not clearly erroneous and are
affirmed.

                4.      Constitutionality of the ACCA’s “Residual Clause”

        “We review de novo a challenge to the constitutionality of a statute.” United
States v. Bowers, 594 F.3d 522, 527 (6th Cir. 2010).

        As discussed, supra Part II.B.1, the language “or otherwise involves conduct that
presents a serious potential risk of physical injury to another” is commonly referred to
as the ACCA’s “residual clause.” 18 U.S.C. § 924(e)(2)(B)(ii). Stafford argues that the
“residual clause” is unconstitutionally vague because its prohibitions are “so indefinite
an ordinary person would not know what conduct it prohibits.” Stafford contends that
the clause is “void for vagueness, as there is no predictable, consistent, or fair definition
that can be applied to the residual clause,” and that it fails to provide defendants with
“any reasonable opportunity to know whether a prior conviction will qualify as a
predicate offense under the ACCA.”

        Recently, in United States v. Perry, 703 F.3d 906 (6th Cir. 2013), and United
States v. Campbell, 482 F. App’x 997 (6th Cir. 2012) (per curiam), this court determined
that the “residual clause” was not unconstitutionally vague. In Campbell, the panel
recognized that the Supreme Court has held the clause to be constitutional and that it
“provides guidance that allows a person to conform his conduct to the law.” Campbell,
482 F. App’x at 997; see also Sykes v. United States, 131 S. Ct. 2267, 2277 (2011)
(stating the residual clause provides “an intelligible principle and provides guidance that
allows a person to conform his or her conduct to the law” (internal quotation marks
omitted)); James v. United States, 550 U.S. 192, 210 n.6 (2007) (observing that the
clause “is not so indefinite as to prevent an ordinary person from understanding what
conduct it prohibits”). Stafford, like the defendants in Perry and Campbell, hopes to
persuade us that the dissents in the Supreme Court’s ACCA caselaw favor a change to
the interpretation of the clause. We are bound to follow Supreme Court precedent.
Therefore, we hold that the ACCA’s residual clause is not unconstitutionally vague.

                               III. CONCLUSION

       For the foregoing reasons, Stafford’s conviction is AFFIRMED and the
district court’s sentence is AFFIRMED.
