United States v. Christopher Weast
2016 U.S. App. LEXIS 1232
5th Cir.2016Background
- Law enforcement used peer-to-peer software to locate an IP address sharing known child-pornography files, downloaded sample files, and identified the ISP subscriber as Larry Weast; officers then executed a warrant at the Weast residence and seized computers from Christopher (“Chris”) Weast’s bedroom containing child pornography.
- Weast was indicted for receipt and possession of child pornography; he sought to represent himself but repeatedly disrupted proceedings and filed sovereign-citizen–style pleadings.
- After competency evaluation, the district court found Weast competent but, based on persistent disruptive pretrial conduct, denied his request to proceed pro se and required him to participate remotely; trial proceeded with court-appointed counsel.
- At trial the government introduced forensic and metadata evidence linking the shared files and device activity to Weast’s computer and accounts; the jury convicted on both counts.
- Post-conviction, Weast raised four constitutional challenges on appeal: (1) Fourth Amendment suppression of evidence obtained via peer-to-peer investigation; (2) Sixth Amendment right to self-representation; (3) exclusion/limitation of his digital-forensics expert’s testimony; and (4) prosecutorial comments allegedly infringing his Fifth Amendment right against self-incrimination.
Issues
| Issue | Plaintiff's Argument | Defendant's Argument | Held |
|---|---|---|---|
| Fourth Amendment: warrantless use of P2P software and IP lookup | Weast: Riley requires warrant protection for digital data; evidence from peer-to-peer download and ISP lookup should be suppressed | Government: IP and files in shared P2P folder were voluntarily exposed to third parties; no reasonable expectation of privacy | Affirmed — no Fourth Amendment protection for voluntarily shared IP/files; Riley inapplicable |
| Sixth Amendment: denial of right to self-representation | Weast: court improperly denied his Faretta request and should have let him represent himself at trial (or remotely) | Government/court: pretrial disruptive conduct showed intent to obstruct; judge may terminate self-representation to preserve courtroom order | Affirmed — denial appropriate given persistent obstructionist behavior; remote participation would not prevent disruption |
| Evidentiary/Sixth Amendment: limitation of expert McGregor’s testimony | Weast: limiting his expert prevented development of hacking/alteration defenses | Government: issues were cumulative and largely developed via cross-exam of government expert; no timely objection was made | Affirmed — plain-error review fails; exclusion of cumulative testimony harmless |
| Fifth Amendment: prosecutorial remarks implying defendant’s silence | Weast: questions/argument suggested guilt from his silence and warranted mistrial | Government: remarks ambiguous, addressed virus/knowledge theory; court promptly gave curative instructions | Affirmed — comments not plainly a manifest comment on silence; instructions and strong evidence cure any prejudice |
