OMG, its so stupid.. I KILLED 10 PPL playing MW2 or I FRAGGED 10 PPL playing MW2, It doesn't mean i have lust for blood and i need to kill, it's a game and while some are taking it to seriously, it's still a GAME, something that should ENTERTAIN, not hurt.
My theory is, it's parents fault that they don't teach children the difference between M-rated titles and those that are meant to be for them. It's because what games LOOKED like, not what was thair purpose. Same is with drinking and any other stuff you can do at age of 16/17/18/21.. While at 17 i can go join army and KILL REAL PEOPLE, i can't have beer.. at least in US... for the love of God, use common sense, unfortunately some people appear to have none..
