Well, I really don't know what to say, the incredible thing is that these massacres continue to happen and every time there are big discussions and talks, and after a month is the same. I don't live in US, nor I ever travel there, but it's clear that there's a problem, I don't know if somebody is doing something, from what I see maybe not.
I've got the feeling that the guilt is always given to the shooter, not to the society. I mean, the shooter IS guilty, but you can examine his situation, his story, when a thing like this happens one time, but when it happens almost sistematically it's clear that the person is not the problem, he surely got some problems, but there is a situation in which his problems can grow and find a tragical epilogue.
