Continuity mistake: When Justin Bieber gets shot, we see him from the back as he falls back, and his left hand is flailing around with no gun in it. We then cut to him from the front falling backwards, and he's holding the gun in his left hand the whole way down to the ground.

Continuity mistake: When Nick is talking to Catherine about what happened at the night of the murder he folds his arms. In the next show they are unfolded.

Continuity mistake: Series 11, Episode 18, "Hitting for the Cycle": At the very beginning of the episode they are talking about the cycle while looking at the board.

The scene then goes out to show the CSIs again, and there are now four cards grouped together on the board.
Revealing mistake: When the bomber is shot in front of the store, he is standing in front of a shop window. It's highly unlikely that the window wouldn't get hit and shatter.
