This is becoming less about the gun issue and more about the mentality nowadays as everyone wants to say that's what it is. Are there really that many mentally ill people in society? Soon anybody who expresses any anger will be reported and brought in for questioning. Shades of Minority Report! There will still be plenty of guns available though.
There will always be angry people, unbalanced people, psychopaths, mother fucking assholes, and people who use poor grammar in any society. It's really nice of us to let them play with guns, I think.
