The US Supreme Court decided this issue last year:
http://www.law.cornell.edu/supct/html/09-5270.ZPC.html
Summary of ruling: Jury selection must be public, unless there is a really darn good reason for it not to be and the court makes it clear on the record what the reason is.
A motion for mistrial, I guess. But I have a feeling that HHJP would make KC go first to avoid that problem.

I don't see this in the Motion in Limine. The media seems to make up a lot of stuff in this case, so unless someone can show me where Ashton actually said this I don't see much point in talking about why he said it lol.
KC's statements in a letter would not be admissible unless they are "admissions"--i.e., not stuff that helps her--or fall within some other hearsay exception/exclusion. I'm not sure what you mean about the letters to Robin being "admitted." Nothing has been admitted yet, because the trial has not started.
