I don't disagree with that, and from what I read it was with the exception his weapon was returned unloaded. I said I think that unloading his weapon was silly and classless. I don't think it rises to the level of criminal nor is it worthy of getting pissed off about. I'm not the victim type. I'd have just called him a pissant and been done with it. I guess other people need to hold on to their anger.
I can't speak for the OP but from what I gathered from reading the thread was that the extended detention (in order to run the OP's firearm's serial number) was the OP's primary complaint, the officer unloading all of the OP's magazines before returning the weapon was just "icing on the cake" so to speak.
Personally I don't blame the OP for being irritated, I was too, law-abiding citizens generally don't like being treated like criminals, especially after it has been determined that no crime had been committed & that they are not criminals.
