Resisting arrest,aggravative assault, sample assault. Where are the charges for the arrest or warrant it nothing it must be something to filed beside letting a judge or jury guess who telling the truth.
I believe that you have already posted a question. You should immediately retain an experienced criminal defense attorney. If you cannot afford one then apply for a public attorney. The attorney will be able to investigate the matter and advise you whether pre trial issues exist and what strategies should be employed. Good luck.
Each county has different use of force requirements. You may be able to get additional information that most public defenders simply don't have time to dig up. I would highly recommend you look into hiring an experienced lawyer to help you with your case. The F2 aggravated assault alone can be up to 5-10 years incarceration. Good luck!
