theres some things you watch on TV that you dont need ANY volume on to know its a load of crap.
fathers day I was at my brothers, dateline was on.. somethin about GTA, they had it on mute but you could tell what message they were trying to get across even without listening to the program.
a combination of good parenting and common sense is all you need to play a game like that responsibly.. unless walmart sells AK-47's in aisle 18, and unlocked BMW Roadsters with keys in ignition on aisle 19, I dont think anyones going to go on a shooting spree for picking up GTA from aisle 17
but back on topic.. when bush is on tv, tv goes off
