Firstly there must have been a (or more) breach(es) of regulations, not necessarily crimes. Although Jack is mentioning not wearing a helmet I cannot find that in the OP, so it might be something else, or more than one thing.
Secondly a major breach of regulations is disobeying a stop order by a police officer. As stated in many western countries one would be in severe trouble, not rarely ending in injuries or worse.
Now this moto lady took all the risks for herself and her passenger and cannot complain about the result of fleeing for the police. Lack of respect for an official service like the police is wrong and bad for any democracy.
The fact that police officers take tea money is a general issue in poor countries where they are not paid very well.
It doesn't harm the offender as it is a cheaper and faster "punishment" than the official version, it doesn't bother me at all when it happens, I always think how much the same offense would have cost me in my country of origin.
Very large sums of tea money were collected in a US state where officers ceased money they found in several offender's cars and never returned it but instead transferred it to officer bank accounts.... how you mean TIT?
Not wearing a helmet is a crime IMO, I agree with Texpat, I once passed an accident site near Nong Han, two people (a couple) lost control of the MB and fell on the road (this is the highway Udon-Sakhon), they were ran over by a pick up and their brains were displayed on the pavement as both didn't wear a helmet! Of course one could say they punished themselves but what about the guy who ran them over with his pick up? He was in shock and totally innocent to the accident.
