re: Nothing New...
Greetings and Salutations.
Here in the USA, It has been long true that Law Enforcement Officers have a simple picture of reality. In their internal model, there are only THREE kinds of people: 1) Cops. 2) Family of Cops. 3) Perps/Criminals. The longer I live, the more I realize that this is the view of LEOs in ALL cultures.
The sort of harassment that you mention happens here too. There are, alas, no good ways to deal with it and get it to stop. Running away used to help, but, in today's world of instant communication, that is less effective. I would suggest that a good defensive measure would be to purchase a notebook, and, record, in ink, every time a stop happens. Write down the date, the time, the badge number of the LEO, if possible, and/or the Unit Number on their vehicle. Also, take time to write down, as exactly as one can remember, what was said. The good news is that there are some excellent, sensitive and reliable digital recorders available on Ebay and other sources that can go a long way towards helping keep that record accurate. This will not make the harassment stop, but, it can be a powerful tool after a year or so if one wishes to use the spotlight of publicity to scare away the LEOs.
In most cases, all one can do is hunker down, and just take it until the predators lose interest and move on to other, more interesting targets.
Pleasant Dreams
