Name me one Corporation, anywhere, that allows its employees to carry weapons into the workplace.
Locally to me, most gun store employees carry as a matter of course. Closer to you, the Scottsdale Gun Club allows their employees to carry in accordance with AZ State law. News stories from several States are cropping up where school Districts are allowing their staff to carry personal armaments.
Still more info here and on just about every gun forum...
So yeah... We're in the minority, but that doesn't make the practice wrong, insane, silly, or inadvisable. Quit to the contrary, we need to do everything we can to get responsible folks carrying everywhere and anywhere.
