Bill Cosby’s lawyers are challenging the legality of the disgraced comedian’s classification as a sexually violent predator. If he is classified as such, he must receive counseling by a state-approved provider for the rest of his life. A judge has yet to rule on the legal challenge. The 81-year-old Cosby is set for sentencing September 24thon three counts of aggravated indecent assault. He plans to appeal his conviction.
