You know I do hope they are kept out of the Courtroom. They are still going to watch the trial. In fact, I hope they disobey the rules and watch the trial. I want them to hear about EVERY single piece of evidence the SA has against ICA. But I don't want them there to display their facial expressions, sneers, sighs, and gestures for the jury to see and to put more pressure on other witnesses.
Plus also keep this in mind. It will be easier for them to throw Cindy and George under the bus. Because to the jury the lack of her parents not being there to support her will gain more sympathy for ICA. They won't know that her parents aren't there because they're not allowed to be there but just that they aren't, and that it's just ICA alone against the world. And against the mean and abusive parents that she's going to allege actually committed the crime.
The DT doesn't want the A's there in the courtroom just as much as the SA doesn't, but their motives are very different.
ETA: No matter if the A's watch the trial in the Courtroom or at home on TV we all know one thing for certain, they're going to lie. So keeping them out surely isn't going to keep these two from lying or somehow will change their makeup to be honest people. And clearly they aren't afraid to lie under oath, we have already seen them do it. They already know they'll never be charged with perjury. Even though I wish they would someday be held accountable.
