I think it needs more than that. It needs an impartial doctor to observe and diagnose anything that has gone on including a full tox screen, xrays and general physical exam for bruises and needle marks.
It also needs the court to appoint a special guardian for that purpose ..not saying she is not capable but someone who will get the best of the best without input from the Jacksons.
Her lawyer is bound to do her bidding, if all he has are suspicious and she refuses to tell him why she is acting like this there isn't much he can do.
That is why I think LE needs to be really involved, not a 5 minute 'ok you are alive and playing cards, goodbye' but a thorough interrogation of all involved.
It almost seems as if its being treated as a family squabble but 3 kids were left home by themselves, at least no one to contact if there was an emergency, no way to reach their guardian if they were troubled or needed to talk, just the woman who has taken the role of mom disappearing.
I will have absolutely no respect for the LAPD if this doesn't get taken seriously
