JFK assassination: New movie has a new theory

The bullet that killed President John F Kennedy in November, 1963 has never stopped travelling. Ever since that fateful day in Dallas there have been dozens of theories about who was responsible for his death.
A new movie called The Irishman offers a new twist to the tragic tale, positing not the who but the why. Starring Hollywood heavyweights Al Pacino and Robert de Niro, it argues that an unholy alliance between the mafia and Teamsters boss Jimmy Hoffa led to his death. Nothing new in that, but what is new is that the President was not their main focus.
