Enough Already! : A PROBLEM OF EVIDENCE: How the Prosecution Freed O.J. Simpson.<i> By Joseph Bosco (Morrow: $24, 265 pp.)</i>

Blah blah blah O.J. Blah blah blah Marcia. Blah blah blah Ito.

I am reminded of the time when Lucy, on the kitchen set of “I Love Lucy,” decided to bake bread. If a little yeast makes a tasty loaf, she reasoned, imagine what a whole boxful will do.

The journalists, pundits and players in the O.J. Simpson case who have written or are writing books now find themselves working from a similar recipe:

Oh, they explain, they’re just shining some light on the judicial system. Their retrospectives simply continue America’s national crash course on justice. And what about the tawdry and lascivious characters of this case? Why, they answer, these are merely the come-ons to fill up this important classroom.

To that, one might say, bull. But even if you accept this argument, when is enough enough? Just about now, I’d venture.

Joseph Bosco, the man who sat in the Simpson courtroom all those months in a neck brace, has now been touched by fame, as he happily tells us in “A Problem of Evidence: How the Prosecution Freed O.J. Simpson.”

A freelance true-crime writer, he veers quite close to unctuous in this chatty, catty, chauvinistic, I-was-there-and-you-weren’t book, telling the case this way:

The prosecution was incompetent; the defense was diligent; the judge was an imperial egomaniac; and the author and some of the writers in the press had a swell time. They became good pals. And, hey, a few of the women along the way were better looking than others.

As for the defendant, Bosco says, maybe the government framed a guilty man.

Lucy, who has the appetite for all this?
