Personally, I don't believe video games, music, etc makes people go on violent rampages and it kinda gets under my skin when something tragic happens and the media or whatever jump all over the most convenient sacpe goat.
For example, a few years ago I was reading the newspaper (a rare event for me, I try and avoid anything to do with news cause it's so damn depressing) and a 14 year old kid killed another with a claw hammer. He said he got the idea from Manhunt which is now banned here in Oz, also thanks in part to some politian getting on her soapbox saying how impressionable kids are, yadda yadda yadda... We've all heard the typical rant they come out with before. Hell if they had their way the only thing the planet would be aloud to play would be pong.
Now, Rockstar have stated time and again that they make games for adults, not children. On the cover of the game it clearly stated in no uncertain terms: MA 15+, Strong voilent themes and all the rest of it. When the parents were asked why they let their child play such a game their answer was that the rating system for games was to confusing. What the f**k is so confusing about an MA rating???
That kid was old enough to KNOW that killing someone was wrong yet he did it anyway. They could give games all the censors and ratings they want, but in the end when it comes to kids playing games and the like, it's up to the parents to decide if it's suitable and control it where they can. I guess what I'm trying to say is people should take responsibility for their actions and not find some half arsed lame excuse to try and get out of it...
