I understand you point that AutoZone need to draw a balance between having access and not having access to a weapon. And Yes just one sociopath or psychotic employee could like so many other examples that we've seen come rushing in and "shoot-up the place and the people in it." But I want to point out that having a gun with a person, and retrieving a gun to do ill, is not something that is limited by a zero tolerance policy. Anyone could come to work without a weapon and on one's lunch break retrieve a weapon and then use it regardless if they had it in their car or not. I hope Mr. McClean is rewarded by those seeing his honor and heroism as a man they want working for them.
