Maybe it's because he's Micheal Jackson! same way O.J Simpson didn't get found guilty.
Im not completely sure about him being guilty or not..but he's been accused so many times! but that could just be people jumping on the bandwagon as well.
IMO both families were looking for money, why else would they be more interested in MJ paying them a big sum of money instead of doing whatever they could to put him behind bars? No money would ever shut me up if my son was molested but both families were quite happy to keep it quiet in exchange for a few millions.
The latest case, the mom even went for waxing and other beauty treatments right after her son told her about the sexual abuse, and they also lied about that same kid having cancer just to get money off celebs.
