Stupidity: The fact that the young mother in the hospital would give Janet (a total stranger to her) her baby to watch while visiting her husband in a different area is completely unreal. Nobody would really ever just give their baby to a stranger like that and leave. In addition, Janet took the baby into Jack's room for quite awhile.
Stupidity: When Kunte/Toby saws himself free from his leg irons, he removes only the one, and then runs off into the night, dragging the other one behind him, which makes no sense, and is quite audibly heard in the near distance.
