Youtube has a lot of videos of British "police auditors" who go to stand near police stations to take videos, get police attention and hilarity ensues. It's worth watching a few of them to get the taste.

We have the same auditors in the states, except that the auditors in the states who do this are often detained illegally by the police, then sue and win, and get paid out of taxpayer dollars with no repercussions for the police whatsoever who acted illegally. One guy in particular I know who used to do this went by TheBattousai or similar name and I believe went through this cycle 2 or 3 times with various police agencies. Not exactly hilarity here
