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.
Chosen answer: You misheard ABH - Assault occasioning Actual Bodily Harm.http://en.wikipedia.org/wiki/Actual_bodily_harm.
