We all know the outcome of the investigation into his island, with his eventual arrest and death. But what became of his staff? You don’t run an operation that large without the help of dozens, or hundreds of people. Most of those people were accomplices to multiple felonies. I’m sure there were a few who didn’t know what sort of operation they were a part of, but many must have. I don’t remember reading about any other arrests other than his. Were there other arrests, and if so, how many? What about his suppliers? The gangs that would sell him slaves, and the human traffickers who smuggled the victims? Did they all get off Scott free?
Disregarding the conspiracy theories, if he had (for example) 10 staff, kept 7 of them absolutely in the dark and away from anything they could narc on and either had dirt on the other 3 or paid them obscene money to not ask questions… those 3 arent coming forward to say what they knew, they are giving the same story as everyone else “I saw nothing”.
This is compartmentalization. Letting people know only what they need to know to be effective, nothing more, and keep the arms of the organization separated as much as possible.
