Under Florida law it is a crime for a person to surreptitiously record another while on the phone. That being said, there is indeed a law enforcement exception and any person surreptitiously recording another at the direction of law enforcement commits no crime. It may very well be a crime for the other person to record you without your knowledge or consent, but there would need to be proof that he wasn't told to do so by a police agent where he resides. If you believe a crime was committed against you then you should report the crime to the police here (using their non-emergency line). Be sure to provide them with any evidence you have.
This is not to be considered legal advice nor does an attorney-client relationship exist.
