Should The Government allow violent video games

I say that no the government should allow people to buy violent video games because in a video game I no its very violent such as Grand theft auto most important and much more. I also think that that game teaches you a lesson because if you play the game and you kill say a cop then you gat stars and the cops come chasing you and 9 times out of 10 they catch you, you either get busted or you die. Also you cant blame the game if someone kills someone else because nobody or nothing could make you do something like that because people make there own choses and thats there problem I mean I feel bad if someone dies over this but its not just the game there maybe something wrong with that person. And thats how I feel about the government letting people buy video games.
