The eleventh-circuit affirmed the defendant’s convictions for possession and distribution of child pornography, rejecting challenges based on the Fourth Amendment, Double Jeopardy Clause, sufficiency of evidence, evidentiary rulings regarding graphic images, exclusion of emails, and jury instructions. The court held that Google’s use of an automated “hash-value matching” protocol to identify a file as child pornography constituted a valid “private search” under *United States v. Jacobsen*, reasoning that the near-perfect accuracy of hash matching provided virtual certainty that law enforcement’s subsequent warrantless review revealed nothing materially more than what the private party had already discovered. The court further ruled that possession and distribution are distinct offenses under the *Blockburger* test, meaning the Double Jeopardy Clause was not violated by convicting the defendant on both counts. Regarding evidentiary and procedural issues, the court found no abuse of discretion in the district court’s admission of child pornography images without prior judicial review, its exclusion of emails regarding a framing theory, and its refusal to provide a specific jury instruction on that defense theory. The court vacated the defendant’s sentence and remanded for resentencing because the district court erroneously applied a five-level “pattern of activity” sentencing enhancement under U.S.S.G. § 2G2.2(b)(5). The court determined that only conduct falling within specific statutory references listed in the Guidelines’ commentary can justify this enhancement; since the defendant’s prior conviction for fourth-degree sexual misconduct was the only qualifying episode and a probation violation involving a different age group did not match the enumerated crimes, there was no valid “pattern” to support the enhancement. Consequently, the court dismissed as moot the defendant’s challenges to his supervised-release-revocation sentence, which is dependent on the underlying sentencing calculation.
