I know I've asked this before but don't recall an answer. Is there some kind of law, whether case law or statutory law that says that jurors cannot be shown on camera? Or is that just a case-by-case thing? Obviously, the people in the courtroom can see the jury as can all the parties in the case. Just wondering if they do this out of politeness, or if by the judge's orders or what the mechanism is. The reason I ask is that I wonder if say a juror is accidentally shown on camera, does it constitute some kind of mistrial mechanism, or anything like that?
