News people always seem to miss the point. Just as when they blame music for suicides, etc. It is not the material that is causing this, or else we would be seeing a tremendous amount of this stuff going on from most people using it. The real issue here is, what is wrong with these people that causes them to self destruct? If it was not one thing, it would be another that pushes them over the edge. They are obviously in need of mental help, unforunately they rarely get it in time.
Edit : And it is far easier for parents to blame games, songs, etc than admit their child had a problem.
