I believe in freedom. You should be free to do with your ARs as you wish. I think it a mistake for the OP to feel guilty about a terrible tragedy of which he had nothing to do with. Where I get upset is when the government decides to punish all law abiding gun owners because of the sins of a few. The gun control steps that governments are taking to supposedly prevent future tragedies and/or lower the gun homicide rate will do neither. For the gun grabbing politicians, what happened in Connecticut was a tragedy, but it was also a huge opportunity to implement their long hoped for gun control policies. The truth is, that politicians, like Bloomberg, Obama, Shumer etc. have been hoping for this moment for a very long time. The Second Amendment be damned. I will keep my "evil assault rifles" as long as I can.
