Executive Action (JFK conspiracy movie 1973)

Kind of a boring movie, unless you're into the JFK assassination. It's a very interesting show, especially having been made in 1973.

From IMDB:
"This fictionalized speculation posits that a covert group of rogue intelligence agents, ultra-conservative politicians, unscrupulously greedy business interests, and free-lance assassins become increasingly alarmed at President Kennedy's policies, including his views on race relations, winding down the Viet Nam War, and ending the oil depletion allowance. They decide to terminate him through an "executive action" utilizing two teams of well-trained snipers during JFK's visit to Dallas and place the blame on supposed CIA operative Lee Harvey Oswald as the lone assassin."
