Corrected entry: Toward the end of the movie when Gary Sinise goes into Mel Gibson's house to collect the reward money and Gary pulls out his gun it is a Glock 9mm. Later when they are fighting and Mel Gibson throws Gary through the glass of the store window and his gun falls out of his hand, it is a Berretta not a Glock 9mm.
Corrected entry: When the female kidnapper tries to force the boy to drink from a bottle, he spits red liquid all over her white shirt. She walks into the next room and the red splatter changes from a scattered spray to one big stain.
Corrected entry: im not sure if this can be considered a mistake since im not familiar with police tactics, but, after the son has been rescued, there are reports on the tv that investigators do not believe that all suspects have been caught and they do not believe the leader has been caught. Since they believe this, wouldnt they fingerprint the place they were keeping the kid in? How could Gary Sinise explain why his fingerprints are all over the place? He only had a few minutes from the time he radioed in to the time the cops showed up, he couldnt say he left all those prints in that little time.
