Conspiracy theorists believe that JFK was the victim of a conspiracy.
 For example, intelligence agencies such as the American CIA and the British MI6 necessarily make plans in secret to spy on suspected enemies of their respective countries, but this kind of activity is generally not considered to be a conspiracy so long as their goal is to fulfill their official functions, and not something like improperly enriching themselves
 While conspiratio can mean "plot" or "conspiracy", it can also translated as "unity" and "agreement", in the context of a group
