@Emilski - I would think that say a case that involved rape or a brutal murder would not be allowed to be broadcast or even a trial that involves a minor.
I also would think that a trial has to fit certain guidelines to begin with and would have to be set up in a way to allow the trial to be broadcast.
Although there may be some judges looking to make a name for themselves, most of the time this is not the case and they could get in trouble for doing so.
That being said I would think that they would be extremely cautious as to allowing a video to be broadcast and I would really like to know what types of guidelines there would be to look for that may allow a case to be broadcast over the air.
I could see the judge allowing a trial to be broadcast for the matter of public record and the fact people may be heavily invested in the trial, but again there are many things that could go wrong and I would like to know what guidelines there are that must be met in order for the trial to be broadcast.
