I think the parent is part to blame, it is a teenage game and has that ESRB rating. Their child is not even old enough to to play such game, and there you go. It's like giving a kid a real gun, when he thought it's just a toy.
and, Left 4 Dead....H*** YEAH! Get your copies asap. It frags big-time. I wonder if this same kid plays it, will he just storm out of the house with his dad's assault riffle and start massacring those people he see thinking they are zombies? :???: lol
