That was one of the most brilliantly executed pieces of legal theater I have ever seen in my life period. What OJ did was to put on the rubber protective gloves in an ill fitting manner. If you look at the video, you see that the rubber gloves did not stretch all the way down to the base of the fingers. Therefore, when he attempted to put on the gloves found the night of the murder he couldn’t pull them on because the rubber gloves underneath them weren’t on all the way either

It was a brilliant piece of showmanship.
