My mom's boyfriend was in Iraq for a while and he killed a few people. He said that the only way he and his buddies could keep from going insane or breaking down was to joke and laugh about it. Maybe these guys are like I would have been and just got a kick out of it, but it's very possible that they're having to be light hearted about it to preserve themselves. I loving hate the media and the way it likes to link completely stupid things together just to scare people.
