Why is it that we must continue blaming movies, music, etc for other peoples violence? A man goes into a theatre playing a premiere of the new Batman movies and kills 12 people, is it the movies fault? Absolutely not.
The writers, directors, nor the actors told this man to do such a thing. He just simply did it on his own. A movie nor music makes someone go and commit a crime, its their behavior and actions that need to be blamed for not the movie or music.
