Revealing mistake: When Daniel (the locksmith) goes home, the lamp next to his daughter's bed is on. After he finally tucks her in, he puts his finger on the light switch on the wall, but it is already in the "off" position. He doesn't flip the switch in either direction, but you hear an audible click, and the lights go out as if the lamp was controlled by the switch. (00:30:02)

Directed by: Paul Haggis
Starring: Sandra Bullock, Don Cheadle, Thandie Newton, Dato Bakhtadze, Karina Arroyave
Factual error: A key plot point hinges on the Iraqi fellow believing he has shot someone but caused no harm. A brief shot of the bullets he has loaded his revolver with reveals that they are black powder blanks. Such blanks produce large clouds of white smoke when fired (indeed, they are used specifically to produce that effect in movies), but the shooting scene shows no smoke at all.
Trivia: Despite receiving top billing, Sandra Bullock has only six minutes of screen time.

Chosen answer: Since he was directly involved with the investigation, to identify the body would have been a conflict of interest. Therefore he had to notify the next of kin beyond himself.
