it makes sense though. going down that road will eventually lead to the banning of violent books.
one from high school classic literature: The Great Gatsby
in the book a woman is run down in the street by a car and left for dead. afterwards, her "husband" goes looking for the owner of the car who he thinks committed the crime, but really didn't, and shoots him to death in his own pool and after all that, turns the gun on himself and commits suicide a couple meters away under a sunshade. if that doesn't fall under the term "violent", i don't know what does, because you wouldn't have to work hard to get that kind of scenario from a GTA game.
