You're welcome! There are more interviews that Ezra did that are on YouTube. The only one I can think of at the moment is a MSNBC one with Chris Hayes. I'm sure I'll think of others later on. I am really looking forward to seeing what he'll work on next.
About Carl not being comfortable, I can see him still not being comfortable to this day with his own defense. I feel like he kind of has to stand by what he's said, but I'm sure he is able to clearly see all the doubt and speculation over the verdict. Like you, I respect the defense team. The way they fought to get him innocent is incredible. Yeah, Judge Ito did continue to practice after this trial. He actually retired just last year. I don't know if he was asked to partake in the documentary. I would imagine he was approached, but declined. Maybe similar to how Ezra approached Carl. I only say that because Carl had said he only accepted to be in the documentary after he talked to Ezra and the producers multiple times about what would be covered.
Oh yeah... OJ was a godawful rapper! haha. I had no idea about the stuff he did post trial. The things he did... wow.
