Mad people are mad, as easy as that. TV, media, games, society or whatever might be the final "trigger" for them to cause harm, but it canot be taken out of context and then blamed on as media now does about video games.
Before video games violent movies and music got the blame for kids beeing mean to eachothers and society.
And regarding America and their politics, a lot could be said about that. For example, selling guns in banks? Close to none weapon controll / check system?
And the right to defend yourself with any means nessesary is so bullshit that.. well no! There must be a ballance somewhere, defend yourself - but if possible try not to blow the ****ing head of the burglas please?
And also, while speaking about the last tragic school shoting, I love how media explains it:
"He was a shy boy who used a lot of his time on the computer, while listening mostly on black metall".
I am not kidding around, the line above was in the local newspaper some days ago.
So everyone who do playing computer a lot and listen on anything else than the Justin Bieber surely got to be ticking bombs?
Again, mad people are mad, and society has a lot of problems - but we canot start pointing fingers and blame ONE singel factor for people to lose their minds.
