If you believe the officer used excessive force, you may sue the officer, the police department, and the municipality for compensation. Note that such suits usually do not win, but that does not mean you cannot win, if the facts are sufficiently in your favor. You should consult with an attorney who has brought similar suits in the past, if possible; if not, experienced criminal defense counsel would be a good choice. Note that if you have not suffered long lasting or permanent injuries, then even if the officer was legally in the wrong, it may not be worth bringing a suit; the compensation you can recover is related to the extent of your injury, and with little injury, you could spend more on the lawyer than you could recover. You may also file a complaint with the police department about the officer's behavior.
