It's just the same rehashed excuses and scapegoats every time...guns made him do it, games made him do it, rock music made him do it, movies and tv's made him do it...how about simply, "The guy is a nut job and he did it, the end."
It just cracks me up how pathetic people some people are. I'm not this pro-gun activist or anything like that, but it amazes me how many people blame guns and groups like the NRA over the actions of a handful of idiots. The wacko in China did the same thing with a blade...Timothy McVeigh did it with explosives...9/11 was hijacked planes...the list goes on and on. Maybe if society stops spending so much time pointing fingers in and treating certain things like a witch hunt then we can start focusing on actual, real ways in looking to help prevent things like this by noticing early on when people have mental/psychological issues and addressing those, rather than blaming rock music for it.
