I had a similar problem a few years ago when I reported a local copper for abusive behaviour. Three in the morning outside my house, he appeared to be arresting a young lad but the copper was shouting and swearing. After 15 minutes I got dressed and went out not expecting the noise to be from the police, waking up the whole street.
After I made a complaint, I was stopped and breathalysed almost every time I went out in the car - seven times one week. I was lucky, a friend of mine was a local inspector and I went to him. The harrassment stopped. John, take it to the top at once. Don't trust them not to find something to get you for. They stick together and care little for your rights if they think they can get away with it.
