Continuity mistake: Keifer initially grabs Ethan's neck with his right hand and pins him up against the wall with it, but for the rest of the scene he's using his left. (01:08:50)
Continuity mistake: When Angelina goes to the scene of the murder witnessed by Ethan, she is seen sitting on the footpath. At the start she has a pad on her left knee and a pen in her left hand. However as the scene progresses, it disappears and reappears several times. (00:23:35)
Visible crew/equipment: At the very beginning after the white van hits Matt, there is a crew member behind a hay stack. (00:05:50)
Answer: As "Costa" was initially a suspect, the police took a DNA sample, which did not match any DNA on file - that was what they meant by "he's clean." It basically means that Asher was very careful at not leaving DNA evidence (other than that of others like Hart to frame them). Presumably the real Costa had no DNA profile linked to his identity on file either, or it could have returned a mismatch and revealed Asher's deception.
