There isn't a tangible and sustainable link between Video games and murder. Most of the most famous killers in history lived in a time before the modern FPS. The way violence works now is a product of a shifting society, not a rise in FPS games.
I certainly don't think so. In fact, contrary to popular belief, statistics show that since the arrival of violent video games, crime has actually dropped by at least 10%. Only a psycho would be inspired by a video game to go kill people. The thing is, though, it's usually these guys who make the headlines and give gamers and violent games a bad name.
Well, statistics show that since all the folks that went gaga over the releases of Halo 3 and Halo Reach didn't go out an kill people, since we're actually chatting on the internet about one crazy guy as opposed to bathing in blood as a result of all the Halo-fueled serial killers out in the world.
Seriously, if there was any truth to your statement whatsoever, we should have been seeing a 1000% increase in serial killers over the last decade or so.
Crazies are made by mental crippling, not art. (And yes, video games are art.)
