Soybomb -
Let me elaborate. I had a friend who had a CCW, and was pulled over by a state trooper. The troopers of that state are issued S&W (some model I don't know about, not being a Smith guy) that have a mag disconnect. My friend informed the trooper that he's carrying legally (required by his state). The trooper asks my friend to step out of the car, and to place his hands on the roof so that the trooper can unload his weapon. My friend complies.
The trooper proceeds to remove the magazine from the Glock my friend carries, and tells my friend he can stand at ease or whatever. My friend is alarmed, and reminds the trooper that there's still a round in the chamber. The trooper tells him that it's okay, because the gun couldn't fire.
That's what I mean by nonchalance - not that someone would point the gun at themselves and then pull the trigger. Either way, I think you'd agree that it's not very informed thinking.
