Posting the obvious

The place I work at has a sign on the door that says "Handguns and oher weapons are not allowed." Exactly who is this for? Anyone crazy enough to bring weapons to work isn't going to be deterred by a sign ... matter how big and official-looking the font is. Might as well put up a sign that says "Unicorn parking in the rear" or "No fat chicks." I guess someone is just covering their ass legally. I'd had to see the lawsuit that would ensue if someone came to work with a machete, a potato gun and a LAWS rocket. "No one told me I COULDN'T!"
