My problem with these studies is that they tend to stick to the flawed premise that a violent game is the sole factor in a individual committing acts of violence. None of them seem to focus on the effects of the broader spectrum of the cliques and communities surrounding these kinds of games. In the past few years we've seen news stories of game players committing acts of violence against others or themselves over video games. And judging from the numerous articles and forum posts we've seen here of late the gaming community seems to be rife with hostility towards women, towards game creators, and other gamers themselves, up to and including threats of murder. From tragic news stories this year we've seen the act of cyber-bullying can lead people to commit suicide. I don't find it much of a logical step that this kind of aggressive behavior could also potentially lead to actions of homicide.
