From what little we know about her I'd agree wholeheartedly with that assessment, this is pure speculation but I think she might be some form of Court appointed wrangler for Chris or some one involved in assessing Just how capable he is the incident he is currently in court for proves Barb is unwilling or incapable of supervising Chris in the manner he needs and he can't be trusted to stay out of trouble on his own.
That's really the only logical explanation I can think of that makes any form of sense.
If she's somehow involved in keeping Chris from getting distressed and people are doing things that, while within their rights, are causing him distress, it's entirely reasonable for someone whose job that is to try to stop it, at least by reasonable means like asking. It doesn't give her or Chris any special rights, and to the extent it's legal, people can obviously continue doing anything legal.
Generally, that would include recording in public where there is no expectation of privacy.
However, my advice about anything in court, whether the courtroom or even the courthouse itself, is just don't record anything unless you have explicit authorization or have been advised by a lawyer who practices in Virginia that this is okay. Violations of recording laws in court are subject to civil and possibly criminal contempt penalties.
There may also be issues with intercepting attorney/client communications, but to some extent, counsel is expected to take reasonable measures not to do things like, for instance, blabbing privileged material in public while someone is openly videotaping.
