...assassination can seldom be employed with a clear conscience. Persons who are morally squeamish should not attempt it.
A further type of division is caused by the need to conceal the fact that the subject was actually the victim of assassination, rather than an accident or natural causes. If such concealment is desirable the operation will be called "secret," if concealment is immaterial, the act will be called "open," while if the assassination requires publicity to be effective it will be termed "terroristic."
- From "A Study of Assassination," a document found in Job 79-01025A, the CIA's case collection relating to its overthrow of President Jacobo Arbenz Guzman of Guatemala, 1954. Appended to the document was a five-page list of assassination targets in Guatemala. The list, naturally, was redacted in full prior to publication.
