This is an old arguement, as old as civilization[almost] ..."Guns don't kill people [anymore than any other item] Idiots, Morons,and the [severely] mentally derranged kill people. Taking away violent games will not stop the insanity.
NOTE: (an analogy) if Video games were what was causing the shootings, Asia would be filled with nothing but perverts and pediphiles (considering the extent of skin on children) shown in thier manga, Anime and other media)
The topic/problem itself is insane..
Definition of insane: doing something over and over again and expecting different results.
The world media rehashes this same debate year after year, in various forms, century after century, not to solve it, but to increase sales of media subscriptions and advertising. Each time, re-releasing it without so much as a different spin, or a coat of paint and each time the public buys it hungerly, as though they've never heard of this happening.. It's 'boy bites dog' headlines and sells readership. pft, suckers, PT Barnum was right, but I knew that already...
