What the court held

Phone-recorded videos were properly admitted on the testimony of the person who made them; no chain-of-custody analysis was required because the recordings were unique, readily identifiable and relatively resistant to change. Where evidence is not readily identifiable and is susceptible to alteration, a more stringent foundation is required — a chain of custody complete enough to make exchange, contamination or tampering improbable. The court also upheld the handling of the defendant's requests to inspect the phone, where the government produced a mirror image rather than the device.

Why

The court applied the settled two-track foundation rule: identifiable items may be authenticated by a witness who recognises them, while fungible or alterable items need custody documentation. It treated the recordings as falling in the first category given the maker's testimony, and noted that the defence examined the mirror image through its own forensic expert and did not press the alteration theory with the witness who made the videos.

Our reading — not the court’s words

Why this matters in practice

Durham is the case that explains why chain-of-custody objections to digital evidence so often fail: courts treat a recording with a live sponsoring witness as identifiable, which moves the custody question from admissibility to weight. The corollary matters for examiners — custody documentation becomes decisive precisely when no witness can speak to the item, which is the ordinary situation for extracted artefacts. It is also a useful precedent on producing a mirror image in lieu of the device itself.
