The message for the CCW is clear: just because you see a gun doesn't mean the guy holding it is committing a crime. Avoid drawing a gun when police are present. If you must draw in public and police show up, do whatever you can to holster or lay down the gun to minimize the chances of mistaken identity and getting shot.
This should be information already known even if you're not into guns or concealed carry. It's common sense.
I was at the casino the other day and went to the high rollers table. I asked the dealer 'what's the minimum bet?' He said, "a hundred dollars." I said what's the maximum? He said, "a box of .45"
