Take it easy, this is not a slight aimed at you.
Cops need shorthand to describe a situation, so they know best how to proceed.
I know! I'll call the police "clean pigs" when they stay in their police stations, and "dirty pigs" when they are abusing the rights of citizens (which is pretty much all the time they are not in the police station).
"Shorthand" goes both ways. Police use anti-gun-owner terminology, so I can use anti-police terminology.
See how that works?
