Who orchestrated JFK's assassination?

Prediction market on manifold. Resolves to the rough consensus among non-US-state-affiliated scholars, researchers, and historians of the identity of the final orchestrator of the assassination of President John F. Kennedy at the start of 2030 (or N/A if no such consensus exists). "Final orchestrator" means the entity most responsible for directly initiating the chain of events that led to the assasination. If the CIA enlisted the mafia to help with the assassination, this will resolve 100% CIA. If the CIA and mafia are co-equal partners in carrying out the assasination, this will resolve 50% CIA, 50% mafia, etc.
