A word commonly used today to refer to the police.

It originated in a few ways. The one I know is that Tupac used punk-police in a few of his songs, and people mistook it as Popo.

"Runnin' from all these punk police..." -Tupac

He says it fast and it sounded like popo.
"Somebody called the Popo?!"
