Good grief! It was Gomer, not Barney who made the citizen's arrest!
BTW, if they had told me to "drop the gun", I would have firmly but politely explained that this was an expensive gun and that I would very slowly lay it down and move away from it where I would happily lay down.
That's funny, that's what I was thinking too. I wouldn't dare drop my pistolas on concrete! I always cringe when they do it in movies. Hell, you might break a Glock thataway!
