Re: dirty jersey cops
Call the Sates Attorneys Office. They handle complaints like that. They may have other complaints on file for him. Also contact the Internal Affairs Division if they have one, Most Police departments do. Then also file a complaint with his superiors.
Did you say he had to pull in front of you making an L shape?
If so this is very unusual type of stop. Not proper training at all. Also aren't cops in your area required to call it in when they make a stop?
The dash cam would show this unusual traffic stop angle, and with the record of him calling your make/model/plate number this might make your case.
At my age being cynical and sarcastic is just making small talk.
