So you are saying parts of the courthouse are off limits to the public already without impacting the public's rights to access-i.e. Judges chambers and clerics office. How hard would it be to have a back hallway and an entry way for witnesses and victims to use that would be private and thus closed off to prying eyes. I don't think the idea would be to close off public access to the courtrooms or most halls-just a few corridors.  (In reality these halls already exist, you don't see the jury trooping off to the jury room through the public corridors.)
