I agree, probably the first call will be against firearms, although I hope not. I oppose that line of thinking for sure, I think the first thing we should take a hard look at is all the tv shows and video games that glorify violence. Flame away, but if you have kids you know that 30 seconds after watching pro wrestling the kids are trying the same moves. Is it any wonder, raise a kid on any one of the tv shows that are crime based, along with a steady diet of ultra realistic video games, throw in some anti-depressants too for good measure.
That may not be the case here, but its just another symptom of a society that is out of balance. So much suffering for so many by the heartless acts of one (as far as we know).
