I saw Cosby perform live several times. His routines were clean and funny. I thought he was one of the rare normal people in Hollywood. I was close. He was normal for Hollywood.
Back in 1970 a friend had a tape of Cosby telling some really funny sports stories. Part of the reason they were so funny is you could tell he had actually participated in them.
Having said that, I had no doubt he was guilty and hope he gets what he deserves.
