I've been to many places where they had the following notice:

The unlicensed possession of a firearm is prohibited on these premises.
(my italics)

I like that sign. It says that a person licensed to carry a firearm is welcome, but the common thug is not. (Not that the thug is going to understand or obey the sign, but it's a nice gesture.)

Many places have the ghostbuster sign. I think that's just to make the sheeple feel better.
