This is a definite slip up.In the middle of the movie, Billy gets in trouble with the terriorists for "being in the shower" and not being ready for the hour to hour head count. The head terriorist, Luis, whips him real bad on his back. The next day Billy shows his friends the cuts and wounds from the beating. Well, a day or so later, or maybe even on the same day,(can't remember for sure)but it wasn't long when Billy's friend, Joey gets permission from the terriorists to leave the school. He dosen't want to and goes outside and grabs a gun and starts shooting. Of course, one of the terriorists on guard fires back. Billy, seeing all this occur, runs to try to stop it. The black guy (T.E.) grabs Billy's back And pulls him away. Billy didnt even flinch. You think that he would though, since he has all those cuts and wounds on his back from his beating. It should of hurt him when the black guy pulled him away, but he showed no sign of that.
