Video game induces violent behaviours?

Right. Whatever. I was riding the bus today and saw a mother with her son, who looked no more than 11 or 12 years old, holding a copy of GTA Vice City. He was 12 at most! (You may be wondering how I manage to figure that out, but I'm assuming most kids over 12 won't be wearing a Batman backpack.) Look, if you parents want to complain about how video games induces violent behaviours and all, that's fine, but perhaps you shouldn't be buying them a copy of those games. That's why there are ratings on those games now. And even if there aren't any ratings on the front cover, you probably shouldn't be buying your child a game that shows a guy with a gun in his hand. So...whatever.
