I have a prior sex crime conviction. A woman that was close to me found out and began blackmailing me to get money. Because of my prior my wife and I went along with it for a year. We got tired of it and told her we would pay no more. She in turn made an outlandish statement to the police and I was arrested. I have been vindicated in the court of law after spending $150,000 due to the patrol officers lack in investigative work. Is this grounds for a lawsuit? If so, what can I sue for and what type of lawyer would I need?
