I am a little disturbed by people who play games whose object is to sneak up on people and kill them, just as I would be disturbed by people who played a game whose object was to sneak up on a woman and rape her. But....
(a) bad taste has never implied violent behavior
(b) I think games like GTA are so over the top and ridiculous that they're more comedic than bad influence
© if there ever has been a case where the producer of a book, song, movie or videogame has been found guilty of contributing to someone's death, I think people have abused that excuse long enough and egregiously enough that people don't take it seriously anymore (and won't until the next big leap forward in interactive media, maybe full-body sensory VR suits, in which case if any of you freaks are still playing Tom Clancy games you can just stay the hell away from me

)
Ultimately, there'll be a small flurry of editorials about these terrible merchants of violence and depravity, a larger flurry of editorials about accepting personal responsibility for your own actions, a few stores will stop carrying the game, and life goes on. Anyway, hasn't GTA: VC become the biggest game in history without Wal-Mart even selling it?
