I wonder if the young man had walked out to his car, gotten his gun, and then taken off his AZ shirt - then re-entered the store and now looking like John Q. Public - if things [legally] might change a bit.
I understand company policy[s] regarding weapons at work. But there are exceptions to every rule and this is a classic case of it.
Real sad side of this is the bad guy got away. I'da shot him without question, as he came in and was holding a gun [read: GREEN Light] - and then would have walked up to him as he lay there leaking his life onto the floor, and double tapped him in the head.
"A dead man can not bear false witness; and is no longer a burden to society. Period. Next case..."
Oh - the double tap to the head - believe it or not this has been told to me by more than one LE officer!
And I concur - AZone lost my business.
