I can tell you are upset, as well you should be. But I would not file a complaint and this is why, it has been my experience that many law enforcement officers threaten many things they simply cannot do, hoping you do not know any better. I absolutely hate that, as I DO know better and when I argue they cannot do something, they only get madder! Figure that? The thing is, they all stick together. There is much truth in that "blue wall." And if you did file a complaint, him and his other fellow officers would keep an eye out for your car if you ever came into the area and you would surely get a ticket for something....probably anything they can stick you with. They are sore loosers with control issues. It is almost as if they feel they are above retribution.
I had a police officer that threw me up against a wall when I simply said to him regarding a response I had with someone, "How do you know, you werent there?" He handcuffed me and since I am very short and they were very tall, I was literally off the ground when they took me to their station. My arm was out of the socket, my wrist was bruised and my little finger was fractured. Definatly abuse of power. All documented by an emergency room report.
But instead of filing a complaint or lawsuit, which I now wish I had done, I wrote his comanding officer and met with their public relations officer. I didnt want some other woman to be treated in such an abusive manner. LIttle good it did me, as I thought it was all over and when I didnt show up for court, they sent officers to my house for failure to appear for something as stupid as disturbing the peace and in the end I had to apologize to the officer! Several years later, this same sherriff was released due to criminal charges against him! They were not the least bit thankful I didnt file a lawsuit and went forward with their issue.
Granted, my situation is a little different than yours and my advice totally does not make any sense, especially after what I told you happened to me. But you did get away with no ticket or anything, so be thankful. Yes, I do realize he probably couldnt have issued a ticket anyway.
Unfortuantely, this is the world we live in. Police abuses left and right. Very little you can do. However, I live in Pittsburgh and they do have a citizens review board. That has helped tremendously with this. Officers overstep their boundaries left and right, day after day and there is very little you can do about it unless they file actual charges, something you can actually fight in court. And even then, they all stick together and it is still very difficult. I know in my situation, they all lied and since it was me against the rest of them, well, you know I had no chance in hell. But that pig sherriff got what he deserved, even if I was not the one that dealt the hand. Usually these people are not only doing it to you, but to others and then it takes some crazy fool to get really mad and POOF....they are shot or taken out of office. So, they get theirs in the end. The good police officers do their jobs well, dont threaten with stuff they cannot do and do not abuse individuals simply because they can.
I know my opinion is very severe, but I did not appreciate being abused in that manner or threatened with stuff they cannot do at other times with other officers. Good luck, just take a breath and calm down. Its not worth it.
