It has happened frequently to me and to people I know unfortunately. One of my friends tried to file a complaint with the local chief of police and they said that in order to file a complaint against an officer you have to give the officer who you’re complaining about your name and address, and it is up to the chief if they want to pursue it further. Not a great system if you’re being targeted by a biased cop. A lot of times with these pull overs, they don’t give tickets so there’s no record and it doesn’t go into the police data. In RI there’s an officer bill of rights that protects them from pretty much anything.
