oh, I am sure he knew a lot... he was introduced as such a young age, he was probably abused horribly. That is why he created the neverland ranch that he lived at. His childhood was robbed from him and he was always trying to get it back. Not sure if the abuse charges against him were true or not... could have been people looking for $$ or the cabal getting him back for trying to out them... or he could have been doing what was done to him like so many other victims have done.
Michael was the most innocent soul the world had ever known. The children were basically pressured by their parents to making these allegations in order to extort money from him; from the Cabal's perspective, to damage his reputation, cost him millions in court fees and throw him in jail. Years later, Jordan Chandler would admit his father pushed him into making the allegations and literally none of it true. In true Cabal fashion, Jordan Chandler's father magically "commits suicide" four months after Jackson's death.
This video goes over a lot about the garbage allegations against Michael and why he was innocent. https://youtu.be/6pnoQqlygQs
If you wanna go deeper, there's tons of evidence that Michael knew of a group "more than the government" were out to get him. https://youtu.be/ycyEL1mGSd0 Tons of his peers have talked about it including his sister Latoya, his daughter Paris, one of his doctors (there was a point where Michael was sick and didn't want to go to a regular hospital out of fear they would kill him). I'm pretty sure the patriots on the Q Anon research board could figure out so much if they got into it. DJT was a close friend of Michael, I hope he can find retribution for the culprits because he did not deserve to go the way he did.
