Like most of the rest of the universe, I can't imagine why O. J. Simpson has done it. Publish his appalling book, that is. There were I think 8 people in the country who actually gave him the benefit of the doubt, and assumed that he must be innocent because he was acquitted. He's just changed all 8 minds.
I've read at least one speculation that he did it because he can't stand not to be in the limelight; he's hooked on the talk shows and seeing his name in the paper. If that's true, he's even sicker than I thought, and I hope the trend continues of refusing to carry the book or air the interviews (except for Fox which will run anything), because that's the real punishment, and the only one that will hurt him.
