Yes. I handle these cases across Florida. The issue is whether the police officer's use-of-force was justified according to the Supreme Court decision in Tennessee v. Gardner. The means that one must examine all the case's facts and the officer's actions based upon the totality of circumstances.
Your son's case would be a violation of his civil rights under USC Title 42 Section 1983.
Please have your son contact one of us today. Unfortunately, we cannot contact him.
I only practice in the areas of personal injury, federal civil rights, and criminal law. I will not respond to inquiries about legal representation in other areas of law, so please do not call me about matters outside my areas of practice. Furthermore, my answers on Avvo do not create an attorney-client relationship. Avvo is not designed for the type of legal analysis I personally require to accept a case. You should always seek a consultation with a licensed attorney who practices in the specific area of law who can fully review the facts of your case.
Too many unknown variables exist to properly answer this question. But I think you should definitely find a civil rights lawyer and have a conversation with him/her. That dialogue will help establish whether this case should be filed.
