And that's a good lesson for all of us. Just because we see a BG with a gun we don't necessarily need to just whip out our Roscoe and fire. A bit of nerve racking patients is needed to wait for a good moment. Wait for that window of opportunity where you can get the drop on them (or failing that, at least something they totally did not expect.)
You guys remember the tape were the motel operator pulled his Glock and waited while the BG demanded money from the clerk. And then surprised the heck out of him with that Glock!
