It is a sad story, luckily l never had a problem with BSOs in my area. They were very understanding, helpful and friendly.
Every officious, meddlesome, overbearing,
public servant gets my dander up, especially the ones which turned into petty tyrants.

I destroyed one a few years ago by systematically recording his conducts after politely pushing him to his limits while recording the conversation, then launching a complaint. When they start to be rude let alone to swear at you they are done! It was undefendable years ago it is even more frowned upon this days.
Also, if he is systematically harrassing others in your area a well documented compliant launched mutually by all the involved parties might be the remedy.
