OJ, makes his own self look guilty without any additional pressure. Therefore I must conclude he done the deed. His book idea is perhaps a desire to get it off his chest without actually admitting to the crime.
The fact is, if he come out and said, "I, O.J. Simpson did in fact murder my ex wife and her boyfriend".., there is nothing that can be done to him because of a legal clause called "Double Jeapordy"..., meaning a man can not be charged twice for the same crime he was acquitted from.
This valid law of protection will no doubt be stricken from the books because of people like him, and many innocent people will end up in prison or death row when this happens. This double jeopardy law was designed to protect innocent persecuted people from eternal persistent vengeance seeking folks.
Unfortunately it obviously protects the guilty as well. What can be done to rectify the matter? Removing the very law designed to protect the innocent. Sad stuff really.
The whole OJ Trial proved one thing - you cant have justice or even escape what you really did, unless you have mega-big $$$ at your disposal. You cant get a fair trial unless you are rich. Even the guilty if they are rich enough can hire the right lawyers.
