Yeah I mean, orchestrating an assassination in a federal prison of a guy the whole world is watching, and never even so much as a whiff of a leak? Because how do you contain that without whacking everyone involved (which we would know about)? You don't. Not without teleportation, time-travel, or at the very least post-hypnotic suggestion.
There were some leaks. Some of the events I would need to check my offline documents for more specific references but, for example, the Reddit leak with a person who was working at the jail saying that he had to let in someone associated with the military and they left shortly after Epstein was killed.
Oh he's smart AF, all right.
