Cannot even entertain the idea that he/she could be wrong about something. In their minds, they are infallible.
Someone who hates fun.
Dude, there was a knife fight in the hall of my apartment. Took the popo 45 minutes to get there. Probably because they wouldn't be able to write anyone tickets, so it wasn't a priority.
Fuck the police.
Thugs will do anything until the Police show up.
They are also infamous for not giving two fucks about civil rights and tricking individuals into thinking they have no rights in a police confrontation (ex. telling a minor they have no rights because they're young, while they actually do.)
The "pig" stereotype came from their pushy, pissed off, bossy attitude. Also came from infamous cases of police misconduct. They are also called "pigs" for being arrogant and thinking of themselves as a gift to society, while a lot of people think the exact opposite.
Police: "We're here to help."
Smart Person: Shut up, you blatant idiot. Do you understand what cops have to go through and how hard they work to make sure idiots like you aren't killed?
Idiot: Shut the fuck up man, what if there were no police! That would be awesome.
Smart Person: You really are scum, you do realize what life would be like without police?
