No, not really. The trial was over. Removing him from the courtroom by placing him in jail accomplishes nothing. Were it in the middle of the case and the judge needed to maintain courtroom decorum, it would be one thing, but the trial was over and he was leaving. What was the point of arresting him and preventing his departure other than just a little power trip on the part of the judge?
This part was left out of the excerpt: Stowers asked to approach the bench and apologize, but the judge told him he could not." I'm sorry that is just wrong.
