In NY the NYPD call them the FEEBS.
There was also the story of three policing organizations arguing over which had the best police dog. So they have a competition. They seeded a house with drugs and sent in a dog from each agency.
The first dog, from the local sheriff’s office went in and came out with a pound of heroin.
The second dog, from the state police went in and came out with two pounds of heroin.
The third dog, from the FBI, came out with nothing and then proceeded to take the heroin found by the other dogs, screwed both of them, and then issued a press release.
