I'm new to this site, and will keep my eye on it.
I was with a fellow while we were out protesting near a local police station, who were keeping their eye on us (not necessarily for us either) and he had a holster barely visible under his hip length shirt. When the police came over to him and asked to see (aheem!) under his shirt, he refused, and as they upped their aggressiveness just enough he revealed the pack of gum that it held.
Too funny, as he said "some guys just can't be to careful." The policeman left with a slight embarrassment.
