The body trail
Ahhh, sort of a lot of loose ends in this movie.
Body #1 Black lady shot on train.
Body #2 kid in car that goes in the river (live? Dead?)
Body #3 The school guard. He takes machine gun fire, but we don't know if he is dead or alive.
Body #4 Mason nutcase dude. We presume he is cooked.
The worst one is #3. The movie ends with cooing, ohing and ahing over the baby, but does he take time to mention that he may have left a half dead security guard at the school? I don't think even with the alarm going off they necessarily would have found him.
