Katherine Jackson's Interview From Arizona: 'I was not kidnapped!'

Katherine spoke on national tv saying she's "devastated" by the "misunderstandings" of her whereabouts and accusations that her children have held her against her will.  Janet and Jermaine whispered to each other a few times during Katherine's speech that she read off of paper.  Mrs. Jackson said:

ON THE 'KIDNAPPING'
There are rumors going around about me that I have been kidnapped and held against my will. I am here today to let everybody know that I am fine and I am here with my children, and my children would never do a thing to me like that, holding me against my will.  It's very stupid for people to think that.

ON THE LOSS OF CUSTODY OF HER GRANDCHILDREN
I am devastated that while I've been away, that my children, my grandchildren, have been taken away from me, and I'm coming home to see about that, also.

ON WHO WAS LOOKING AFTER HER GRANDCHILDREN
Before I left I put everything in order with the appropriate people to take care of my children for me and it's really bad to hear that what's going on at home, and the children have been taken away - but I know that... I'll get there in time to get them back. And after I finish this, I will be on my way home.

ON WHERE SHE WENT
I am grateful for my children that they saw that I needed rest and they wanted to take me away for a while, just a short vacation and rest up.
They have taken good care of me and have made sure that I got the rest that I needed.

ON WHY DIDN'T SHE CALL?
One reason I haven't called is I just gave up my phone and I didn't want to have any phone calls while I was here.

 My question is why she would leave her young grandchildren without letting them know where she was going and when she'd be coming back. It's obvious these children have major trust issues and for good reason their father is dead and the only person Michael every really trusted was his mother Katherine.
