Character mistake: When Brooks and Devlin talk to Teddy, the forensic scientist, Teddy puts his rubber glove on incorrectly, with the thumb hanging off the pinkie side of his hand. (00:09:45)
Deliberate mistake: Because the opening narration was adapted from the original American series, the phrase describing the role of the Crown Prosecutors (e.g. "prosecutors who prosecute") is redundant.
Character mistake: In the second murder scene Dalston is listed as being in E6 when it is actually in E8.

Continuity mistake: When Devlin and Brooks approach Richie Newman, and Devlin shows him his ID badge, his hand jumps from the top of the wallet to the bottom. (00:08:00)
