How about this:
Record all the conversations you have with the police, with or without them knowing.
If they don't know you're recording them, and they're being very unprofessional etc, or downright rude etc, just wait till they've gone after fining you.
Make a copy of the recording.
Go down to the cop shop, find the cop. Tell them you have a recording, show them the recording. If they mention its illegal, and can't be used in court, say that you know: 'But wouldn't it be terrible if this got leaked to 'A current affair, or today tonight'? Why wouldn't that be the kind of thing that would ruin a police officers career?'
Hmmmmm, I live in a fantasy world.
