Found this quite interesting for a few reasons.
Firstly, the interview with a copper who says that Fake police are not their problem as they are not police. Who does he think should deal with people pretending to be police men? Monks?
The same rozzer, very young with a high rank by the way, calls bribery a "hole in the system" because people do not want to go and pay at the cop shop, they are doing them a service by letting them bribe their way out.
The same said copper also says openly that the police chiefs are ordering illegal stops and charges so they can kit quotas. He says that the cops themselves get 40% of the fine for issuing REAL tickets. So, if your fine is 400 baht, your bribe should be in the 160 baht level because that is all the rozzer personally gets from it - Real tickets are piece work for the coppers - the more they issue the more they make. I do wonder though why the cops then take less than the 40% for a bung if they get more for from the real tickets?
Over all though, the young would be reporter, sums it up perfectly. The Thai people do not like the corruption when the camera is facing them, but when it is not, it is them who are fueling the corruption because it is easier and cheaper.
Takes two to tango.
