I am old enough to remember going to see the MOVIE Executive Action in the THEATRE. I was just catching up from last night.
Here is the plot: At a gathering in June 1963, shadowy industrial, political and US intelligence figures discuss their growing dissatisfaction with the Kennedy administration.

Fellow conspirator James Farrington, a black-ops specialist, labels this as "executive action". He shows the group that magnicide is indeed a viable option. He refers to the Lincoln, Garfield, and McKinley assassinations as examples
