How would history and culture change if the circumstances surrounding the deaths of Lincoln and Kennedy were reversed? In this hypothetical timeline:
1. Lincoln is killed while riding in a parade by a lone nut with a rifle. The assassin is then murdered before he can be questioned by authorities, leading to a multitude of conspiracy theories surrounding Lincoln's death.
2. Kennedy is killed at the theater by a famous actor. The murder is part of a larger conspiracy to decapitate the Kennedy administration with simultaneous attempts also being made on the lives of Lyndon Johnson and Bobby Kennedy, both of whom survive. JFK's assassin is killed during a shootout with police officers trying to take him into custody, but the rest of the conspirators are caught, tried, and convicted.
