That could very well be but I tend to think that a qualified Psychiatrist would hesitate to make a diagnosis based solely on a video. A very good Psychiatrist can easily tell if someone is faking but that requires face to face session over the course of several hours or days.
To me he looked like he was drugged or suffering from sleep deprivation or perhaps both. But IMO, if he’s acting, he’s a very good actor. If I were going to “act” or fake crazy for the judge and the cameras, I’m not sure I’d think to be so subtle about it. If I were going to act “crazy” I’d jump up and yell and scream and “act” really crazy. But then again, perhaps he is indeed a very good actor. But for now, I’m going to withhold my very unqualified and amateur opinion on that until I hear what those more qualified to make that diagnosis have to say.
