There have been violent games of one sort or another ever since gaming began. Seems bizarre that this particular game is being singled out - especially as it is the second in the series, and indeed there have been other Call Of Duty titles before that, and there are many, many war-orientated games like this on the market.
Bottom line is that anyone who would play such games and then go out and repeat the same scenario in real life is f****d in the head to start with.
Video games, violent movies, music with so-called 'hidden' messages etc do not create mindless killers, yet this seems to be the attitude that the media love to portray.
For this scenario to be true, that such games will encourage people to go out and kill people so the game must be banned, then this posits the notion that EVERYONE is susceptible to this influence, and we could all be killers.
But yet millions and millions of people play such games and DON'T go out and repeat the same in real life. Yet it only takes one or two idiots to create a furore. And these are indeed disturbed individuals, but then again they always were.
Look at this from another angle - if video games are that influential, what about people who play driving games, and hair around tracks knocking other cars off the road, crashing, performing stunts etc - do these people go out and do the same on our roads?
