Harmlessness of “Knowledge” Mens Rea Instructions, Limits on Mental-Health Context, and Lay Testimony on Call Routing in § 875(c) True-Threat Prosecutions

Introduction

In United States v. Richard Colvin (11th Cir. Aug. 26, 2026) (per curiam) (not for publication), the Eleventh Circuit affirmed a conviction under 18 U.S.C. § 875(c) for transmitting an interstate communication containing a threat to injure. The prosecution arose from a telephone call in which Colvin allegedly told a pastor he would “come up there and f*cking kill” him during a discussion involving Colvin’s ailing mother.

After a mistrial in the first trial, Colvin was convicted in a second trial and appealed, raising three issues: (1) whether the jury should have been instructed on recklessness as the mens rea for “true threats” after Counterman v. Colorado; (2) whether the district court unconstitutionally limited mental-health evidence (PTSD and sexual-abuse history) via a motion in limine; and (3) whether a telephone company employee improperly offered expert testimony (interstate routing) while labeled a lay witness.

Summary of the Opinion

  • Jury instruction (mens rea): The panel held that even if Counterman v. Colorado makes recklessness sufficient in true-threat cases, instructing the jury that the government had to prove intent or knowledge (a higher mens rea than recklessness) was at most error in Colvin’s favor and therefore harmless.
  • Mental-health evidence: Limiting testimony about Colvin’s PTSD and history of sexual abuse did not violate the right to present a complete defense because Colvin did not pursue an insanity defense, did not link the evidence to negating the mens rea he actually disputed, and the evidence risked becoming impermissible “context” amounting to excuse/justification rather than legal negation of guilt.
  • Lay vs. expert testimony: The phone company employee’s testimony about routing was admissible as lay opinion grounded in professional experience; and, alternatively, any misclassification as lay (instead of expert) was harmless because Colvin had notice from the first trial and the district court indicated the witness would qualify as an expert in any event.

Disposition: Affirmed.

Analysis

Precedents Cited

1) Standards of review and harmless error

  • United States v. Gibson: Framework for reviewing jury instructions as a whole and avoiding reversal for isolated imperfections.
  • United States v. Anderson and United States v. Singer: Deference to district court wording/style when the law is accurately reflected; refusal of a requested instruction reverses only if correct, not substantially covered, and essential to the defense.
  • United States v. Seabrooks: Harmlessness for instructional error—whether the error contributed to the verdict.
  • United States v. Thompson and United States v. McGregor: Abuse-of-discretion review for motions in limine/evidentiary rulings.
  • United States v. Shamsid-Deen: De novo review when an evidentiary issue implicates constitutional questions.
  • United States v. Moore: Harmlessness for evidentiary error—whether it had a substantial and injurious effect on the verdict.
  • United States v. Chafin: De novo review of sufficiency and Rule 29; affirm if any reasonable jury could find guilt beyond a reasonable doubt.
  • United States v. Henderson: Distinguishing lay versus expert opinion; also applied for harmless error principles in the lay/expert context.

2) Mens rea for “true threats” under § 875(c)

  • Elonis v. United States: § 875(c) lacks express mens rea, but federal criminal liability requires a mental-state component; negligence (“reasonable person” standard alone) is insufficient; mens rea satisfied by purpose or knowledge, while the Court did not decide if recklessness suffices.
  • Counterman v. Colorado: First Amendment requires a subjective mens rea in true-threat cases; recklessness is enough—conscious disregard of a substantial risk the statement will be taken as a threat. It also distinguishes recklessness from knowledge (practical certainty).
  • Wade v. McDade (en banc): Reinforces that recklessness entails subjective awareness of the risk posed by one’s conduct.
  • United States v. Nerey: Government must prove each element beyond a reasonable doubt.

3) Right to present a defense; mental-health evidence limits

  • United States v. Hurn: Core Eleventh Circuit framework for when exclusion of defense evidence can violate constitutional rights; also rejects attenuated “context” evidence lacking a legal link to an element/defense.
  • United States v. Ahmed: No constitutional violation in excluding cumulative evidence.
  • United States v. Mitrovic: Right to present a defense is not absolute; evidentiary rules are permissible if not arbitrary or disproportionate.
  • United States v. Lewis: Relevance definition (Rules 401/402).
  • United States v. Westcott: Psychiatric evidence can negate mens rea if it focuses on specific state of mind at the time of the offense.
  • United States v. Litzky: Exclusion of psychiatric/intellectual-disability evidence upheld where it was not tied to inability to form mens rea at the relevant time and risked confusing excuse/justification with legal negation.

4) Lay versus expert opinion (Rule 701 vs Rule 702) and disclosure

  • Great Lakes Ins. SE v. Wave Cruiser LLC: Lay opinion cannot provide specialized explanations beyond an untrained layperson’s capacity.
  • United States v. Williams: Professional experience can support lay opinion if it is rationally based on experience rather than scientific/technical knowledge.
  • United States v. LeCroy: Classification turns on the nature of testimony, not on whether the witness could qualify as an expert.
  • United States v. Gbenedio: Recognizes the “blur” between lay and expert when testimony arises from professional work.
  • Tampa Bay Shipbuilding & Repair Co. v. Cedar Shipping Co., Ltd. and United States v. Hamaker: “Particularized knowledge” from experience can be lay testimony; straightforward compilations/explanations may remain lay.
  • United States v. Stahlman: Even if testimony should have been treated as expert, Rule 16 disclosure errors can be harmless absent prejudice, especially with pretrial notice and likely admissibility as expert anyway.
  • United States v. Spila: A forensic accountant’s descriptive testimony about records and basic mechanics was not expert; illustrates how courts police the boundary while allowing experiential explanations.

Legal Reasoning

1) Mens rea instruction: knowledge vs recklessness after Counterman

Colvin asked for a recklessness instruction: that the government must prove he “consciously disregard[ed] a substantial risk” that the communication would be viewed as a true threat. The district court instead instructed that the government must prove Colvin sent the message with “intent to communicate a true threat or with knowledge that it would be viewed as [a] true threat.”

The panel’s reasoning proceeds in two steps:

  1. Counterman sets a constitutional floor, not a ceiling. Under Counterman v. Colorado, recklessness is “enough” for the First Amendment in true-threat cases. The panel treated “knowledge” as a more culpable mens rea than recklessness, consistent with Counterman’s own mens rea taxonomy.
  2. Any deviation was harmless because it increased the government’s burden. If the jury was required to find intent/knowledge rather than recklessness, the instruction did not prejudice Colvin; it made conviction harder, not easier. Applying United States v. Seabrooks-style harmlessness principles, the panel concluded any potential instructional error did not contribute to the verdict.

Separately, applying United States v. Anderson, the panel found no “serious impairment” of the defense because Colvin’s theory was categorical denial (“I didn’t say it”), not a claim that he spoke but lacked subjective awareness that his words would be taken as threatening.

2) Mental-health evidence: relevance and the “vital link” requirement

Colvin argued that excluding PTSD and sexual-abuse-history testimony prevented a complete defense. The panel rejected this, relying heavily on the analytical structure from United States v. Hurn (what categories of evidence a defendant is constitutionally entitled to present) and its limitation that evidence too attenuated from an element/defense may be excluded.

Key reasoning points:

  • No insanity defense pathway. Colvin did not provide notice under Fed. R. Crim. P. 12.2 and did not claim inability to appreciate wrongfulness under 18 U.S.C. § 17(a), so the excluded evidence could not be justified as insanity evidence.
  • No mens rea negation as the case was tried. Although United States v. Westcott allows psychiatric evidence to negate mens rea when focused on state of mind at the time of the offense, the panel found Colvin did not supply the “vital link” (in Hurn’s terms) connecting PTSD/trauma to the contested element in his chosen defense posture. Because he primarily disputed uttering the threat, not his awareness of threatening character, the proffered mental-health narrative did not make a material fact more or less probable.
  • Risk of “excuse/justification” confusion. Echoing United States v. Litzky, the panel characterized the excluded evidence as tending toward impermissible excuse/justification—context that might generate sympathy but not a legal reason to acquit.
  • Harmlessness/prejudice not shown. Under United States v. Moore, Colvin did not show substantial prejudice from the limitation given the defense he actually presented.

3) Telephone-routing testimony: admissible lay opinion and, alternatively, harmless expert misclassification

Colvin challenged the admission of Media-Com employee Christopher Welch’s testimony that the call traveled in interstate commerce, arguing it rested on technical engineering data and should have been expert testimony requiring Fed. R. Crim. P. 16(a)(1)(G) disclosures.

The panel upheld admission primarily on a “professional experience” lay-opinion theory:

  • Drawing from Tampa Bay Shipbuilding & Repair Co. v. Cedar Shipping Co., Ltd., United States v. Williams, and United States v. Hamaker, the court treated Welch’s testimony as “particularized knowledge” from years of work, describing business records and how calls are transferred.
  • While acknowledging that lay/expert lines can “blur” (United States v. Gbenedio), the panel found Welch’s testimony largely descriptive and tied to his job-based perceptions rather than a scientific/technical methodology.
  • To the extent any parts drifted into hypotheticals, the panel deemed them rationally grounded in experience and not enough to require expert treatment in this case.

As an alternative holding, the panel applied a United States v. Stahlman-style harmlessness analysis: Colvin had prior notice because Welch testified similarly in the first trial; Colvin attached that transcript to his own motion in limine; and the district court indicated it would have admitted Welch as an expert if requested. Thus, any Rule 16 or Rule 701/702 misclassification did not prejudice substantial rights.

Impact

  • Mens rea instructions post-Counterman: The decision signals that in § 875(c) cases within the Eleventh Circuit, an instruction requiring knowledge (or intent) regarding the threatening character will likely survive appellate review even if recklessness is constitutionally sufficient, because it increases the prosecution’s burden and is therefore difficult for a defendant to show as prejudicial error.
  • Strategic consequences for defense theories: The opinion underscores that admissibility of mental-health evidence often turns on the defense’s own theory of relevance. A defendant who denies making the statement faces a harder relevance showing for psychiatric “context” evidence aimed at subjective perception of threatening nature.
  • Constrained “complete defense” arguments: By emphasizing United States v. Hurn, United States v. Mitrovic, and United States v. Litzky, the panel reinforces that constitutional rhetoric cannot be used to bypass ordinary relevance rules where the evidence mainly invites sympathy or excuse rather than negating an element.
  • Lay testimony by technical employees: The ruling continues the Eleventh Circuit’s permissive approach to “experience-based” testimony about business/operational systems as lay opinion, while still leaving room to deem any overreach harmless when there is strong notice and likely expert admissibility anyway.

Note: The opinion is labeled “NOT FOR PUBLICATION,” so it is not binding precedent, but it is instructive as a practical application of Counterman v. Colorado and Eleventh Circuit evidence doctrine.

Complex Concepts Simplified

“True threat”
A statement that, in context, communicates a serious expression of intent to commit violence. The First Amendment does not protect true threats, but Counterman v. Colorado requires proof of a subjective mens rea at least as demanding as recklessness.
Mens rea (mental state): recklessness vs knowledge
Recklessness means the speaker is aware there is a substantial risk others will perceive the statement as a threat and speaks anyway. Knowledge is more demanding: the speaker is aware to a practical certainty the statement will be taken as a threat.
Harmless error
Even if a trial court makes a mistake, an appellate court will not reverse if the mistake did not affect the verdict (instructional harmlessness discussed via United States v. Seabrooks; evidentiary harmlessness via United States v. Moore).
Motion in limine
A pretrial request to admit or exclude certain evidence. It is typically reviewed for abuse of discretion (United States v. Thompson).
Lay opinion (Rule 701) vs expert opinion (Rule 702)
Lay opinion must be based on a witness’s perceptions and helpful to the jury, and it cannot depend on scientific/technical/specialized knowledge. Expert opinion depends on specialized knowledge and triggers qualification and reliability requirements.
Insanity defense vs psychiatric evidence negating mens rea
Insanity (under 18 U.S.C. § 17(a)) is a specific affirmative defense requiring proof the defendant could not appreciate the nature/wrongfulness of his acts, and it requires notice under Fed. R. Crim. P. 12.2. Separately, psychiatric evidence may sometimes be used to negate mens rea if it is tightly tied to the defendant’s specific state of mind at the time of the offense (United States v. Westcott).

Conclusion

United States v. Richard Colvin affirms a § 875(c) true-threat conviction by applying three reinforcing themes: (1) after Counterman v. Colorado, instructing on a higher mens rea (knowledge/intent) than constitutionally required (recklessness) is, if anything, favorable to the defense and thus typically harmless; (2) mental-health narratives are not automatically admissible as “context” and must be legally tethered to an element or defense actually in dispute, consistent with United States v. Hurn and United States v. Litzky; and (3) operational testimony by industry employees may be treated as lay opinion when grounded in experience, with misclassification often rendered harmless where notice and likely expert admissibility exist.

For practitioners, the case highlights how appellate outcomes can turn less on abstract constitutional doctrine and more on trial posture: the defense theory chosen will control relevance, the instruction’s mens rea level will control prejudice analysis, and the witness-disclosure record will control harmlessness.
