This is nothing new with respect to police misbehavior. The only brave move is to do nothing. Do not answer questions or respond to intimidation.
Fighting back is for later, not in moment of intimidation. Record and write down everything you can about the incident. Police officers in a front of judge are not always believed.
Make sure you’re insisting not on compensation but on receiving a public apology. This is disgrace to all police officers.
