WTF?

I've been trying my hardest not to get sucked in to the Michael Jackson craziness...but I have to say I am shocked that his kids are being given to his parents? Are they not already responsible for raising around nine really messed-up adults? Has his father not already acknowledged having beaten and mentally abused his kids, and if I'm not mistaken - also sexually abused his daughters? And his mother knew all this and stayed silent, watching her kids suffer? How on earth can they be given custody of three more children???
