The Bikini Bottom Police Department is the name law enforcement entity in Bikini Bottom. This includes officers, wardens, prison guards, SWAT Team, and riot guards. They keep the streets clean in Bikini Bottom like actual police officers. They first appeared as officers in Hall Monitor, asking Patrick if he has seen SpongeBob, or the "Maniac". The Prison Warden appeared in The Inmates of Summer, when he was working at Inferno Island along with Barney the Prison Guard. The SWAT team was seen in The Thing, where they appeared to handle Smelly (Squidward), after attempting to attack Patrick. The prison guards appeared in Doing Time when Mrs. Puff was constantly calling them to come and get SpongeBob and Patrick when they were trying to get her to make a jail-break. It should be noted that some cops have been shown to be rather dimwitted. (ex. In Keep Bikini Bottom Beautiful, one officer kept assuming that Squidward was littering while it was clearly the other citizens).
The Bikini Bottom Police Department has established multiple locations to base their operations, as well as places to contain offenders of the law.
Police Headquarters
The station is where the cops stay and receive calls for crimes, which is seen in Life of Crime. They have a dispatcher unit somewhere in Bikini Bottom as well.
Bikini Bottom Prison
It is revealed in The SpongeBob SquarePants Movie that they have a prison for tiny criminals such as Plankton, in which he was taken to at the end of the movie.
The jail holds the regular criminals, for simple crimes such as littering, as the The Tattle-Tale Strangler had to stay for littering outside of the Krusty Krab, it holds major criminals as well, such as Plankton for trying to steal the Krabby Patty Formula, in which he has a pad-locked cell, which he easily breaks out of, as seen in Krabby Road.
Inferno Island is a high security prison, located in the middle of a body of water. The only way to get to it is to go there from the dock-yard, on a metal boat, to make sure there are no possible ways for prisoners to escape and swim to shore. The island is very harsh and the prisoners must sleep on hard beds with flat pillows.

When he was put in the police car, he exclaimed "Karen!!! Help!!!". Strangley, the policeman tilted Plankton's head forward and said "Watch your head" when Plankton had plenty of room fitting in the car due to his small stature.
