Looks like good rulings.
A joint trial for all four is a huge blow to the defense, particularly for the 3 that are only charged with aiding and abetting.
I do not see where they could possibly find a location where media coverage would have had no impact.
Allowing cameras was wise. Whatever verdict results, more people will understand why that verdict was reached.
They are going to have a terrible time selecting jurors, and sequestering the jury will not help with jury selection. It may be necessary to avoid outside influence, but if there is an acquittal, the jury will have paid the highest penalty for what happened.
