If violent media resulted in a maladjusted and violent society we'd have exterminated each other by now after all those years of Bugs Bunny and Roadrunner cartoons, war films, westerns, etc. And it's funny give how violent the world used to be pre-media and how violent crime is continually descreasing. So that pretty much invalidates these loaded, political puff pieces they call studies.
