Serial killers such as David Berkowitz (Son of Sam) smile a lot when arrested and while in court.
Can’t remember his name but that one black man was so out of control that the judge was forced to make him watch from closed circuit TV next door. He screamed every few minutes while in the courtroom.
A small handful of videos of other defendants in court.

That was that black dude who recklessly and with intent drove through a Christmas parade route in a Jeep a year or so ago and murdered several white people including children by swerving to run them over. The female judge assigned to the case acted like he was some kind of god and allowed him all kinds of latitude and leeway in attacking her during the trial. I actually felt sympathy for the prosecuting team that had to sit through that travesty listening to him run his sick stupid mouth. Yes she eventually had to sequester him in a separate courtroom by himself because he kept interrupting her and kept forcing her to have to excuse the jury so he and the judge could go at it out of earshot of the jury as the rules required. He tried to twist the rules as much as possible to exonerate himself. The judge was in way over her head and allowed this murderer to lead her around by the nose. She was a leftwing twerp and had no damned business sitting on the bench as a judge. Wouldn’t even have qualified for traffic court. But that is the state of our judicial system these days.
