At the end of the movie when Mr Brook's (Costner) calls Det Atwood (Demi Moore) on her cell from his cell, watch her partner in the background. She tells him to pick up the phone and listen in. So, he very quietly picks up a standard desk phone and "listen's in" on the conversation. First of all, you can't listen in on a cell phone conversation and how dumb is it to make us try to believe that even if you could, it could be done on a desk phone?
