James Rummel blogs extensively on Public Bathrooms and Concealed Carry.

He points out that many people insist upon unloading their weapon before placing it beyond "direct physical control", but that doing so in a public restroom may do more harm than good:

Anyone who has watched a few action films knows the distinctive sound of an autoloader slide as it ratchets back and forth, and most people would take it as an aggressive or threatening act if they heard someone loading up their gun before emerging from a stall at the mall. (I know I would!) If you don't want to start a panic, then you are going to have to forgo that important safety step.

I mean, he shot photos for illustrative purposes and all. Blogging initiative at its finest. Go look.
