I did like and watch "The Cosbys" every Thursday night at 8 on NBC in the 80s. It was great and showed a "normal" black family, with educated parents (he played a doctor) and five smart kids. None of them were 'ghetto' and it was one of the most popular shows in America. Before that I watched the cartoon Fat Albert, and my brother was a big fan of it. But when the black comedian Hannibal Buress 'broke' the story about Cosby's rape via joke, I started to follow that story. Then a dozen women stepped forward. On the cover of the New Yorker magazine was about 35 women on the cover I stopped and bought it read it. He's been so far accused of 60 rapes and sexual abuses by women using drugs. There are simply not that many women liars. There certainly can be individuals of all "races" who are psychologically "deviant" as true psychiatric diseases is a mental disorder that exists inside the human brain, the grey matter.
I don't know about OJ, and the government certainly hounded him down and set him up in Vegas just to put him in prison. That "sting" operation was wrong, deliberate, and venegful. Yes, I watched the trial and before that the car chase on live TV. But his trial was a trial and he got off and was not convicted. Cosby though was found guilty, and one of his last victims, Andrea Constant, a black woman, wrote a book about it.
