Hey someone had to play the devil's advocate.
I have been to a few places around the world, recently a trip to India and Pakistan a few times. Needless to say that atrocities happen everywhere, and will continue to happen.
It is the way with our world, at times kind and at times extremely cruel. It is the balance of life.
Venting frustrations in thread can certainly help one to blow off steam but expecting that something can be done about it straight away by taking away guns, is naive and wishful thinking.
I really would love to never hear of another event like this but the sad outlook of reality is that it most probably will.
