I suggest you give this a read about arguably Bostons most famous criminal. He had just be transferred to a new max security prison and was killed the same day, the officers had no idea about it.

Epstein was the supplier of children to some of the most powerful people in the world, the president of the united states isn't the only person who can get a sophisticated hit carried out. Trump arguable didn't have the most to lose as he wasn't someone who stayed on Epsteins island. But yeah he could have had it done as could a number of disgusting excuses for men. Andrew Neil who I love has flown on this fuckers plane if Epsteins black book is true.
