Two brothers in California strangled and dismembered their mother, and obviously it is the result of watching The Sopranos. I can't begin to express how messed up that last statement is. Anybody who kills and dismembers anybody is a pretty twisted fuck. If you don't have some of that instinct in you, watching a TV show isn't going to push you over the edge.
The obvious connection the article draws between this murder and watching the Sopranos isn't exactly going to help the case of video games' alleged connection to violent behaviour (i.e., Columbine) either.
