"If I was to put my hands in my pockets, I could be arrested for carrying concealed, deadly weapons!"
- Ernest P. Worrel
Any kind of carry is absolutely verboten where I work. Not even the security guards have guns. Therefore, I don't carry here. I have trained in karate, jiu-jitsu, and aikido off-and-on for about twenty years, though, so that's what I would use if I needed it.
The best weapon is the one between your ears, anyway.
