Police Corruption in Honduras

I've been stopped by the police twice before and fined (Kazakhstan and Mexico) but in both instances I'd been doing something wrong and didn't mind paying up. Today I was allegedly caught speeding, although the policeman who stopped me couldn't tell me what speed I'd been doing and other cars seemed to be pulled over at random. The 'fine' started off at fifty pounds. I decided to waste as much of his time as possible and he eventually got bored and got in his car to drive off, but he still had my log book and driving licence. The licence was a copy, which he could've kept, but I needed the log book back. He suggested twenty pounds. I gave him three. He wasn't happy. Neither was I. In future I'll make sure all my documents are fakes.
