Jestin Tafolla, through counsel, applies for a certificate of appealability (“COA”)
to appeal from the district court’s denial of his 28 U.S.C. § 2254 habeas application. We
deny a COA and dismiss this matter.
Background & Procedural History
Mr. Tafolla was convicted after a jury trial in state court in Oklahoma of
(1) assault and battery with a dangerous weapon after two or more felonies and
(2) possession of an illegal weapon. He was sentenced to life in prison. His convictions
arose from a road rage incident that led to a physical altercation between Mr. Tafolla and

Dennis Clayton. Mr. Tafolla struck Mr. Clayton repeatedly on the head while wearing
brass knuckles. Two police officers intervened after observing the incident. Mr. Tafolla
proceeded to trial. He testified in his defense. Several witnesses also testified at trial,
including the two police officers. Mr. Clayton was not present at trial, but his out-of-
court statements were introduced at trial through the officers’ testimony.
The Oklahoma Court of Criminal Appeals (“OCCA”) affirmed on direct appeal.
Mr. Tafolla then filed a state post-conviction relief application in the Tulsa County
District Court, which was denied. The OCCA also denied the post-conviction appeal.
Mr. Tafolla then filed his § 2254 habeas application in federal district court. The
application listed three general grounds for relief, including several subclaims. The
district court denied Mr. Tafolla’s application, determining some claims were
procedurally barred and the remainder failed on the merits.
COA Standard
Mr. Tafolla needs a COA to appeal from the district court’s denial of his § 2254
application. 28 U.S.C. § 2253(c)(1)(A). To obtain a COA, Mr. Tafolla must make
“a substantial showing of the denial of a constitutional right.” Id. § 2253(c)(2). This
standard requires a petitioner to “show that reasonable jurists could debate whether (or,
for that matter, agree that) the petition should have been resolved in a different manner or
that the issues presented were adequate to deserve encouragement to proceed further.”
Miller-El v. Cockrell, 537 U.S. 322, 336 (2003); see also Slack v. McDaniel, 529 U.S.
473, 484 (2000).
2 Appellate Case: 25-5050 Document: 25 Date Filed: 05/13/2026 Page: 3
Under the Antiterrorism and Effective Death Penalty Act (“AEDPA”), when a
state court has adjudicated the merits of a claim, a federal district court may grant habeas
relief on that claim only if the state court’s decision “was contrary to, or involved an
unreasonable application of, clearly established Federal law, as determined by the
Supreme Court of the United States,” 28 U.S.C. § 2254(d)(1), or “was based on an
unreasonable determination of the facts in light of the evidence presented in the State
court proceeding,” id. § 2254(d)(2).
Procedurally Defaulted Claims
We begin with the claims the district court denied as procedurally defaulted.
Those claims are based on prosecutorial misconduct; ineffective assistance of
trial counsel for failing to object to prosecutorial misconduct and failing to introduce
dash-cam evidence at trial; and ineffective assistance of appellate counsel for failing to
challenge trial counsel’s ineffectiveness regarding the dash-cam evidence.
Because the district court dismissed some claims on procedural grounds, we will
grant a COA as to those claims only if the applicant can demonstrate both “that jurists of
reason would find it debatable whether the petition states a valid claim of the denial of a
constitutional right and that jurists of reason would find it debatable whether the district
court was correct in its procedural ruling.” Slack, 529 U.S. at 484. A state-court decision
is contrary to clearly established federal law if the state court (1) “applies a rule that
contradicts the governing law set forth in Supreme Court cases,” or (2) “confronts a set of
facts that are materially indistinguishable from a decision of the Supreme Court and
nevertheless arrives at a result different from that precedent.” House v. Hatch, 527 F.3d
3 Appellate Case: 25-5050 Document: 25 Date Filed: 05/13/2026 Page: 4
1010, 1018 (10th Cir. 2008) (brackets and internal quotation marks omitted). A
state-court decision involves an unreasonable application of clearly established federal
law “when it identifies the correct governing legal rule from Supreme Court cases, but
unreasonably applies it to the facts.” Id.
We see no basis for a COA on the procedurally defaulted claims. “The first task of
an appellant is to explain to us why the district court’s decision was wrong.” Nixon v.
City & Cnty. of Denver, 784 F.3d 1364, 1366 (10th Cir. 2015). But Mr. Tafolla only
asserts that his procedurally defaulted claims “should not be summarily brushed aside.”
Appl. for COA at 5. He has not challenged the district court’s procedural default
findings, nor has he asked to excuse his procedural default. Under these circumstances,
we must conclude Mr. Tafolla has waived any challenge as to the procedurally defaulted
claims. See Sawyers v. Norton, 962 F.3d 1270, 1286 (10th Cir. 2020) (“Issues not raised
in the opening brief are deemed abandoned or waived . . . [as are] arguments that are
inadequately presented . . . .” (internal quotation marks omitted)). We deny a COA on all
procedurally defaulted claims.
Claims Evaluated on the Merits
We now turn to the claims that the district court reviewed on the merits, which
Mr. Tafolla attempts to challenge in his appellate materials.
Confrontation Clause Violation
In his COA application, Mr. Tafolla argues that his Sixth Amendment
Confrontation Clause rights were violated because Mr. Clayton’s statements were
erroneously admitted at trial in violation of the Confrontation Clause. Mr. Tafolla raised

procedurally defaulted claims.
Claims Evaluated on the Merits
We now turn to the claims that the district court reviewed on the merits, which
Mr. Tafolla attempts to challenge in his appellate materials.
Confrontation Clause Violation
In his COA application, Mr. Tafolla argues that his Sixth Amendment
Confrontation Clause rights were violated because Mr. Clayton’s statements were
erroneously admitted at trial in violation of the Confrontation Clause. Mr. Tafolla raised
4 Appellate Case: 25-5050 Document: 25 Date Filed: 05/13/2026 Page: 5
this claim on direct appeal. The OCCA reviewed the argument for plain error because
Mr. Tafolla objected at trial on evidentiary grounds but did not raise a Confrontation
Clause objection. The OCCA concluded Mr. Tafolla’s Sixth Amendment rights had been
violated, but that plain “error . . . [did] not necessarily require relief.” Aplt. App’x at 122.
“Given the constitutional nature of [the] claim,” the OCCA explained it “must decide
whether [the error] was harmless beyond a reasonable doubt.” Id. (citing Chapman v.
California, 386 U.S. 18, 24 (1967)). In Chapman, the Supreme Court held that “before a
federal constitutional error can be held harmless, the [reviewing] court must be able to
declare a belief that it was harmless beyond a reasonable doubt.” Chapman, 386 U.S. at
24. The OCCA reviewed the properly admitted evidence from trial and found “that the
violation of the Confrontation Clause contributed neither to Tafolla’s conviction nor to
the punishment assessed; it was harmless beyond a reasonable doubt.” Aplt. App’x
at 123. The district court agreed and denied a COA. According to the district court,
reasonable jurists would not debate the correctness of its assessment, given the
substantial evidence of Mr. Tafolla’s guilt independent of Mr. Clayton’s statements that
were introduced at trial.
We discern no error. “When a [state court’s] Chapman decision is reviewed under
AEDPA, [we] may not award habeas relief under § 2254 unless the harmlessness
determination itself was unreasonable.” Davis v. Ayala, 576 U.S. 257, 269 (2015)
(internal quotation marks omitted) (emphasis in original). “And a state-court decision is
not unreasonable if fairminded jurists could disagree on its correctness.” Id. (internal
quotation marks omitted). Rather, the habeas petitioner “must show that the state court’s
5 Appellate Case: 25-5050 Document: 25 Date Filed: 05/13/2026 Page: 6
decision to reject his claim was so lacking in any justification that there was an error well
understood and comprehended in existing law beyond any possibility for fairminded
disagreement.” Id. at 269-70 (internal quotation marks omitted). Mr. Tafolla has not
shown that the OCCA’s harmlessness determination was unreasonable under this
standard. As the district court explained, the OCCA correctly analyzed Mr. Tafolla’s
argument under plain-error review on direct appeal. The district court’s analysis included
a thorough review of the trial evidence to explain why the introduction of Mr. Clayton’s
out-of-court statements was harmless. That evidence included: testimony from two
detectives regarding their observations of Mr. Tafolla beating Mr. Clayton, the recovery
of brass knuckles after the incident, the injuries Mr. Clayton sustained, and Mr. Tafolla’s
own testimony that he hit Mr. Clayton with brass knuckles. Applying the applicable
standards, and discerning no error, we thus deny a COA as to this claim. See Slack,
529 U.S. at 484.
Prosecutorial Misconduct: Statements Made in Closing Argument
Mr. Tafolla requests a COA on his allegations that prosecutorial misconduct
during the government’s closing argument at trial deprived him of his right to a fair trial.
Mr. Tafolla properly raised the following prosecutorial misconduct claims regarding the
prosecutor’s remarks during closing arguments: (1) arguments to the jury about
protecting society from Mr. Tafolla; (2) statements that Mr. Clayton would have been
killed without intervention and that he was afraid to testify at trial; and (3) referring to
Mr. Tafolla as a predator.
6 Appellate Case: 25-5050 Document: 25 Date Filed: 05/13/2026 Page: 7
Mr. Tafolla made this argument on direct appeal. The OCCA reviewed for plain
error and found no prosecutorial misconduct based on the prosecutor’s closing arguments
because: (1) the prosecutor did not improperly invoke societal alarm, per Oklahoma state
law; 1 (2) the prosecutor’s comments were based on evidence presented at trial; and
(3) the prosecutor’s statements did not amount to misconduct under plain error review.
The district court determined that the OCCA’s decision was not contrary to clearly
established federal law.
Reasonable jurists would not find the district court’s assessment of this claim to be
debatable. See Slack, 529 U.S. at 484. For Mr. Tafolla to obtain habeas relief on his
prosecutorial misconduct claims, he must demonstrate that the prosecutor’s misconduct
was egregious enough to render the “entire proceedings against the defendant
fundamentally unfair.” Smallwood v. Gibson, 191 F.3d 1257, 1275 (10th Cir. 1999). In
evaluating the alleged misconduct, the court considers the totality of the circumstances.
Id. at 1276. Mr. Tafolla has not raised any argument in his COA application to suggest
that the district court’s rejection of these claims was wrong.
While it may have been inappropriate for the prosecutor to refer to Mr. Tafolla as
a predator, as the district court reasonably observed, Mr. Tafolla has identified nothing in
1 Tafolla’s direct appeal relied on state law. In Oklahoma, “prosecutorial argument invoking societal alarm is improper.” Terrell v. State, 425 P.3d 399, 401 (Okla. Crim. App. 2018); see also McElmurry v. State, 60 P.3d 4, 34 (Okla. Crim. App. 2002) (“The prohibited ‘societal alarm’ argument is one that mentions crimes committed by other persons and not attributable to the defendant on trial. . . . [I]t implies that the jury should ‘make an example’ out of the defendant on trial to deter other potential criminals.”). 7 Appellate Case: 25-5050 Document: 25 Date Filed: 05/13/2026 Page: 8
the record to suggest this comment rendered the entire trial fundamentally unfair. We
thus deny a COA as to this claim. See Slack, 529 U.S. at 484.
Ineffective Assistance of Counsel
Mr. Tafolla also seeks a COA for his claim that his trial counsel was ineffective
for failing “to object to the admission of evidence or object to the prosecutor’s
misconduct on numerous occasions.” Appl. for COA at 5.
Strickland v. Washington, 466 U.S. 668 (1984), governs ineffective-assistance
claims. Under Strickland, the applicant must show (1) “that counsel’s performance was
deficient” and (2) “that the deficient performance prejudiced the defense.” Id. at 687.
The first prong requires an applicant to show “that counsel made errors so serious that
counsel was not functioning as the ‘counsel’ guaranteed . . . by the Sixth
Amendment.” Id. The second prong requires a showing “that there is a reasonable
probability that, but for counsel’s unprofessional errors, the result of the proceeding
would have been different.” Id. at 694. “When a habeas petitioner alleges ineffective
assistance of counsel, deference exists both in the underlying constitutional test
(Strickland) and the AEDPA’s standard for habeas relief, creating a doubly deferential
judicial review.” Harris v. Sharp, 941 F.3d 962, 973 (10th Cir. 2019) (internal quotation
marks omitted). “Under this double deference, we consider whether there is any
reasonable argument that counsel satisfied Strickland’s deferential standard.” Id. at 974
(internal quotation marks omitted).
8 Appellate Case: 25-5050 Document: 25 Date Filed: 05/13/2026 Page: 9
Ineffective Assistance of Trial Counsel
Mr. Tafolla seeks a COA on whether his trial counsel was ineffective for failing to
offer exculpatory evidence and for failing to object on numerous occasions at trial. As
discussed, his claim regarding trial counsel’s failure to offer exculpatory evidence is
procedurally defaulted. We turn now to whether a COA is warranted on his claim that
counsel was ineffective for failing to raise objections during trial.
The OCCA addressed this claim on postconviction appellate review under
Strickland and determined that Mr. Tafolla’s claim failed because he could not show that
his trial results would have been different but for counsel’s actions. The district court
denied habeas relief on this claim because Mr. Tafolla had not shown that the OCCA
unreasonably applied Strickland or unreasonably determined the underlying facts. The
district court noted that the results at trial likely would not have been different, as there
was significant evidence presented against Mr. Tafolla to support the guilty verdict.
Reasonable jurists would not debate the district court’s conclusion. Mr. Tafolla
argues that his appellate counsel raised several claims of ineffectiveness of trial counsel
on direct appeal. He appears to assert that the number of ineffective assistance arguments
raised on direct appeal demonstrates that trial counsel was, in fact, ineffective, and that
the number of transgressions amounted to prejudicial cumulative error. But the claims
raised on direct appeal were unavailing, and Mr. Tafolla offers no argument or
explanation to refute the resolution of those claims, outside of describing them as
unreasonable. Under these circumstances, he has not shown that reasonable jurists would
9 Appellate Case: 25-5050 Document: 25 Date Filed: 05/13/2026 Page: 10
find the district court’s assessment of his claim debatable or wrong. See Slack, 529 U.S.
at 484. We deny a COA on this claim.
Ineffective Assistance of Appellate Counsel
Finally, Mr. Tafolla seeks a COA on whether his appellate counsel was ineffective
for failing to raise the following challenges on direct appeal: (1) an Eighth Amendment
challenge; (2) additional prosecutorial misconduct challenges; and (3) the trial court’s
failure to instruct the jury on the lesser-included offense of assault and battery.
Mr. Tafolla raised these claims in his state post-conviction relief application, and the
OCCA determined that these arguments failed under Strickland because he could not
show prejudice. We evaluate claims of ineffective assistance of appellate counsel under
Strickland. See Smith v. Robbins, 528 U.S. 259, 285 (2000). To support a finding that
appellate counsel was ineffective, Mr. Tafolla must demonstrate that (1) counsel’s
performance was deficient, and (2) that deficient performance was prejudicial. See
Strickland, 466 U.S. at 687. For counsel’s performance to be prejudicial, Mr. Tafolla
“must show a reasonable probability that, but for his counsel’s unreasonable failure”
to raise the identified issues, “he would have prevailed on his appeal.” Smith, 528 U.S.
at 285.
The district court found that the OCCA did not unreasonably apply Strickland
because Mr. Tafolla could not demonstrate that the results of his appeal would have been
different under Strickland’s prejudice prong. The district court reasoned that:
(1) Mr. Tafolla’s sentence was within the statutory range; (2) the evidence introduced at
trial established that he used a deadly weapon; and (3) there was “strong evidence of
10 Appellate Case: 25-5050 Document: 25 Date Filed: 05/13/2026 Page: 11
Mr. Tafolla’s guilt” presented at trial, and raising other arguments of prosecutorial
misconduct on appeal would not have demonstrated that the trial outcome was
fundamentally unfair.
Reasonable jurists would not debate the district court’s resolution of this claim.
Mr. Tafolla fails to offer any specific argument challenging the district court’s
determination that he could not demonstrate prejudice. He does not address the relevant
habeas standards, and instead “urges” us “to give this issue closer scrutiny.” Aplt.
Opening Br. at 10. Without any specific argument on appellate counsel’s ineffectiveness,
Mr. Tafolla cannot show that reasonable jurists would find the district court’s resolution
of this claim debatable or wrong. See Slack, 529 U.S. at 484. We deny a COA on
this claim.
Conclusion
We grant Mr. Tafolla’s motion for in forma pauperis status.
We deny Mr. Tafolla’s application for a COA and dismiss this appeal.
