KEVIN M. BINKS,

Defendant-Appellant.

No. 00-4175

(D.C. No. 00-CR-180-K)

(D. Utah)

ORDER AND JUDGMENT*

Before EBEL, BALDOCK, and KELLY, Circuit Judges.

Kevin Binks appeals his convictions for shooting a wild horse and lying

about it to federal agents and to the grand jury. Specifically, Binks was convicted

by a jury of one count of possession of a firearm by a convicted felon in violation

of 18 U.S.C. § 922(g)(1), one count of malicious harassment of wild horses in

violation of the Wild Free-Roaming Horses and Burros Act (“Wild Horses Act”),
- 2 -

16 U.S.C. § 1338(a)(3), one count of willful and malicious injury, inhumane

treatment, and causing the death of a wild horse in violation of § 1338(a)(3,6) of

the Wild Horses Act, three counts of giving false statements to a federal agent in

violation of 18 U.S.C. § 1001(a)(2), and three counts of knowingly making a false

statement before a grand jury in violation of 18 U.S.C. § 1623(a). On appeal,

Binks argues insufficiency of the evidence, admission of improper evidence, and

prosecutorial misconduct. Finding no error, we affirm.

DISCUSSION

A. Sufficiency of the evidence

Binks challenges the credibility of one government witness and the

reliability of another. In assessing these challenges, we review the record de

novo, viewing the evidence in the light most favorable to the government. United

States v. Haslip, 160 F.3d 649, 652-53 (10th Cir. 1998). We will reverse for

insufficiency of the evidence only if no rational factfinder could have convicted

on the charge. United States v. Hanzlicek, 187 F.3d 1228, 1239 (10th Cir. 1999). 

We may not consider the credibility of witnesses, Haslip, 160 F.3d at 653,

although we must disregard trial testimony that is inherently incredible or

impossible on its face, United States v. Pike, 36 F.3d 1011, 1013 (10th Cir. 1994),

that is, testimony which involves “facts that [the witness] physically could not
- 3 -

have possibly observed or events that could not have occurred under the laws of

nature.” Tapia v. Tansy, 926 F.2d 1554, 1562 (10th Cir. 1991). In view of these

principles, Binks’ arguments are unavailing.

Christopher Wilkinson testified at trial that he was with Binks throughout

the weekend camping trip during which the two of them harassed wild horses and

Binks shot a wild horse. In arguing that Wilkinson’s testimony was inherently

incredible and impossible, Binks relies primarily on garden-variety challenges to

Wilkinson’s credibility. Further, the fact that two days after the shooting a park

ranger was unable to find evidence to corroborate Wilkinson’s assertion that

Binks fired three shots and that the horse had appeared to fall when shot is

inadequate to show that Wilkinson’s testimony was impossible on its face.

Bureau of Land Management agent Rudy Mauldin testified at trial that

Binks lied to him when he interviewed Binks during Mauldin’s investigation of

the horse shooting and harassment. Binks argues that Mauldin’s testimony should

have been excluded because Mauldin neither tape recorded the interview nor

asked Binks for a written statement. Binks offers no authority for this argument,

and we reject it.

Binks also argues that Mauldin’s questions were ambiguous because, during

the interview, Mauldin was confused about the name of the person that Binks was

camping with on the weekend in question. A conviction for knowingly making
- 4 -

false statements must be reversed if the underlying question was fundamentally

ambiguous, one without a meaning upon which persons of ordinary intellect could

agree. United States v. Farmer, 137 F.3d 1265, 1268-69 (10th Cir. 1998). 

Fundamental ambiguity is the exception, not the rule, and an otherwise ambiguous

question is acceptable if its context clarifies which meaning was intended, or if

there is evidence showing what the question meant to the defendant when he

answered it. Id. Applying these principles, Binks’ argument fails. Mauldin

began the interview by telling Binks that his purpose was to ask Binks about the

September, 1999 shooting of a wild horse. (ROA IV 136.) Binks’ interview

answers demonstrate that he correctly understood Mauldin’s questions. (Aple B.

33-34.) The details he provided were consistent with the weekend of the shooting

and inconsistent with the earlier camping trip that Binks now claims he thought

Mauldin wanted to know about.

Because Wilkinson’s testimony was not inherently incredible, Mauldin’s

questioning was not fundamentally ambiguous, and there was evidence to show

that Binks correctly understood the questions that he was answering, we conclude

that the evidence was sufficient to sustain Binks’s convictions.

B. Admission of evidence

Binks argues that the district court improperly admitted irrelevant evidence

calculated to appeal to the emotions of the jury. The district court’s evidentiary

rulings are reviewed for abuse of discretion. Haslip, 160 F.3d at 653. 

Evidentiary issues that were not objected to at trial are reviewed for plain error

only. United States v. Lindsay, 184 F.3d 1138, 1140 (10th Cir. 1998). 

Binks argues that the district court should have excluded testimony

establishing the identity of the horse that was shot. Various witnesses testified

without objection that they were familiar with the horse from prior visits to the

area. Binks asserts this evidence was irrelevant. We disagree. The evidence

tended to show that the horse one witness saw on the road moments before Binks

and Wilkinson drove up was the same horse that another found shot the next

morning. Further, the fact the horse was so familiar to others suggested Binks

lied in telling the grand jury he had never seen it in his many visits to the area. 

Binks next challenges admission of evidence of the horse’s suffering. He

did not object to any of the evidence that was admitted. He now argues that the

horse’s suffering was irrelevant absent evidence that Binks knew of or intended

it. Again, we disagree. This testimony was relevant to establish the timing of the

shooting and to show that Binks fired the shot that caused the death of the horse.
- 6 -

Next, Binks contends that Mauldin and another federal agent improperly

testified that Binks was not credible and that Wilkinson was. Although testimony

which does nothing but vouch for the credibility of another witness is improper,

United States v. Charley, 189 F.3d 1251, 1267 (10th Cir. 1999), the statements

here instead consisted of the witnesses’ unadorned observations of the actions and

demeanor of Binks and Wilkinson. Neither agent gave an opinion as to their

credibility or truthfulness, instead merely describing their observations and

allowing the jury to reach its own conclusions. Binks offers no authority

suggesting that such testimony is inadmissible, and we perceive no error.

Finally, Binks asserts that a wild horse specialist’s testimony regarding the

harm that generally flows from chasing and harassing horses was improper. We

cannot say that the district court abused its discretion. The testimony was brief,

dispassionate, and likely helpful to the jury in assessing whether chasing the

horses constituted harassment.

Accordingly, we conclude that Binks has failed to show that the district

court abused its discretion by admitting any of the challenged evidence.

C. Prosecutorial misconduct

Because defense counsel did not object to the prosecutor’s statements he

now challenges, we review for plain error only. Binks can only prevail if he can
- 7 -

show that the trial court plainly erred in failing to conclude that the prosecutor’s

argument was improper, denied him a fair trial, and influenced the verdict in light

of the trial and the jury instructions. United States v. Maynard, 236 F.3d 601, 606

(10th Cir. 2000). This Binks plainly cannot do.

Binks argues that the prosecutor improperly emphasized his past felony

conviction. While it is true that the prosecution may not prejudicially exploit

prior convictions, United States v. Dean, 76 F.3d 329, 335 (10th Cir. 1996), no

such improper conduct occurred here. After two permissible comments in the

first minutes of a four day trial, the prosecutor scarcely mentioned Binks’s felony

status. Binks also argues that the prosecution misstated the appropriate standard

for reasonable doubt. We need not decide whether the prosecutor’s statements

were improper because it is clear that Binks is not entitled to relief. The oral

argument at issue did not mischaracterize any evidence, did not clearly invite the

jury to ignore its instructions, and was offered in response to the defense’s own

arguable characterization of the reasonable doubt standard. The trial judge

properly instructed the jury on the meaning of reasonable doubt, and he instructed

the jury that they must be governed by the jury instructions rather than arguments

by counsel. The jury is presumed to follow its instructions. Weeks v. Angelone,

528 U.S. 225, 234 (2000). Finally, the evidence of guilt was overwhelming and

there is no probability that the jury’s verdict was affected by the argument.

CONCLUSION

For the foregoing reasons, we AFFIRM.
