I think it's great news that O.J. has written a book about how he would have killed his wife and Ronald Goldman, if he were the killer. As anyone who reads or watches a lot of whodunit crime thrillers like CSI or Criminal Minds or Wire In The Blood knows, the key to catching an insane killer is to get inside his head and understand what he was thinking before, during and after the murder. That O.J. has reached this stage can only be viewed as a testament to how serious he is about his quest to find the real killer or killers and bring them to justice. It should also be recognized for the impressive achievement that it is; typically a person has to be borderline insane themselves in order to inhabit the mind of a killer so thoroughly and completely, so for a sane and peaceable fellow like Mr. Simpson to pull it off is nothing short of amazing.
...Or maybe he just figured out a way to cash in on having committed a double murder without actually admitting to it, but only a hardened cynic could believe that.
