Like I said some seem to only see the perfect wild west scenario where good guy blows away the bad guy.

A more likely scenario in a chaotic moment going down is good guy unloads a full clip most or all missing bad guy and instead killing other good guys. Then good guy is blown away any way. Other good guys who remain standing had better disarm within seconds or face being shot by LE.

BTW, my bro in law is in the SS. He met one of the first in to that theater in CO. Said it was a complete blood bath. Also agrees that armed civilians would only magnify the problem for them.
