The prosecutor in the OJ case lost it. Never should have moved the case out of the Santa Monica area to downtown. A Santa monica jury would have convicted him. The downtown jury would have acquitted OJ even with a signed confession.
If they would have just made a mockup hand and fit the glove on it, it would have shown OJ attempt to put the gloves on was just a phoney show. But the jury was looking for any reason to aquit, so they might have found another one anyways.
