A client comes to your office. Right off the bat he admits that he is a convicted felon. He tells you last week he was arrested on his way home from work by police in Orlando, Florida. The charge is possession of a firearm by a convicted felon. He says that he told police the reason he carries the weapon is that he works in a bad area in town and needs it as protection. Find me a case indicating whether there is an exception to the ban on convicted felons carrying a firearm. Is the client correct that he should be able to carry it for defensive purposes?
