That site is from the perspective that MJ is dead, so of course everyone around him is suspected of evil. They believe the various news reports and take them at face value rather than reading between the lines with hoax glasses on, like we do here. I agree if Trent really was abusing anyone he would have been gone pronto. If Trent took the video of the siblings on the Calabasas property, then he's doing so with MJ's request for hoax purposes. IMO
MJ dead or alive, the answer changes everything.
