I saw this on another board...I'll say the same thing I said there.
That's always been one of my worst nightmares. An armed robbery goes down with 2 or more robbers with 2 or more CHL's there. The only people who know who the BG's are, are the BG's. Everybody else is going it alone and would have no idea who was on their side or who was there to rob them.
I know it's supposed to be funny, but it does give one something to think about.
Either way, its a good reminder that you should take cover first, then observe, then draw if necessary.
