⁣One of the best "Conspiracy" movies ever made:

⁣In Seattle, Washington, television journalist Lee Carter witnesses the assassination of presidential candidate Charles Carroll atop the Space Needle. A waiter armed with a revolver is pursued and falls to his death while a second waiter, also armed, leaves the scene unnoticed. A congressional committee decides the killing was the work of a lone assassin. Three years later, Carter visits her former boyfriend, an anti-authoritarian Oregon newspaper reporter named Joe Frady, claiming others must have been behind the assassination as six of the witnesses to the killing have since died and she fears she will be next. Frady does not take her seriously; however, Carter is soon found dead of a drug overdose.
