"You can do far more damage in a crowd with a 9mm pistol and large mag than you can do with an AR"

Seriously?  After Newtown and Orlando you actually believe that? if so you are the last person on earth who does, excluding well-trained terrorist and US white male teenagers. Next you will say how much damage you could do with a knife compared to a Glock.

I'm not a gun expert as far as types…thank goodness… I have other interest in my life  other than coddling heavy toys that kill.
