" In his book, originally titled If I Did It, subsequently published as I Did It when the Goldman family won the rights based on their civil suit, O. J. Simpson recounts the killings of his ex-wife Nicole Brown and her friend Ronald Goldman as if O.J. had actually committed the crimes. From my perspective of forty-plus years in law enforcement and behavioral analysis, this book, written years after O.J.’s acquittal for the murders, was just another display of Mr. Simpson’s contempt for moral standards, his sense of power over and remaining anger at Nicole. In other words: the actions of a sociopathic narcissist. "
