There is probably some validity in what he says but he also has the benefit of hindsight AND he doesn’t seem to focus on what I think was the real problem - the bias and contempt of the judge. This judge was biased, he knew it and that’s why he didn’t allow it (the trial) to be videoed so that the public (and I guess higher courts) couldn’t see his demeanor.
The trial wasn’t televised because NY trial rules don’t allow it.
