Why is it never just the fault of the individual, there always has to be something that forced them to do it. This kind of mentality really gets on my wick.
At the end of the day people need to accept that some people are just plain wrong, they choose to do these things, ultimately because they want to.
If it was down to a particular, game/movie/activity, then there would be a lot more of this stuff happening.
Until people stop trying to make excuses for these people and actually place the blame with the person doing the crime, things are not going to get better.
Beer - because this sounds like a pub rant.
