I read Portrait of a Killer: Jack the Ripper Case Closed by Patricia Cornwell. It was her theory on who Jack the Ripper was.
For those who aren't familiar, between August and November of 1888, a man named Jack the Ripper strangled and mutilated five prostitutes and the crime was never solved.
Everyone knew what happened, she was never suspected of having anything to do with the murders, she wanted to close the books on the murders that were never solved - her book never offended anybody.
OJ was accused of killing these two poor people. He was found not guilty, meaning they couldn't prove it, and he wants to release a book on how he would have killed them, had he done it, and describe his act in graphic detail.
BIG difference between the two!
