"In 1967 United States Air Force Colonel George P. Freeman is quoted as saying, "We have checked a number of these cases ... By posing as Air Force officials and government agents they are committing a federal offence. We sure would like to catch one." (Clark, 321)
A classified U.S. Air Force memorandum from 1960 also reinforces the fact that there was high-level interest in reports of impostors: "Information, not verified, has reached HQ USAF that persons pretending to represent the Air Force or other Defense establishments have contacted citizens who have sighted unidentified flying objects. In one reported case an individual in civilian clothes, who represented himself as member of NORAD, demanded and received photos belonging to a private citizen. In another, a person in an Air Force uniform approached local police and other citizens who had sighted a UFO, assembled them in a school room, and told them that they should not talk to anyone about the sighting. All military and civilian personnel and particularly Information Officers and UFO Investigating Officers who hear of such reports should immediately notify their local OSI offices." (Randles and Hough, 160)
In 1965, Rex Heflin, who took some famous UFO pictures, reported that "two men, claiming to be from NORAD, arrived at the witnesses' home and asked to borrow the original Polaroid prints." (Condon, 449) Heflin turned the first three of the four photos over to the two men. NORAD denied that any of their employees had ever visited Heflin, at least in any official capacity. The three photos were not returned to Heflin until 28 years later when in 1993, Heflin received two phone calls from an unidentified woman telling him to check his mailbox where he found the three photos in an unmarked 9x12 inch manila envelope."
I believe that some of these "MIB's" turned out to be agents from the CIA's Domestic Contact Division, and that the Agency was running its own UFO investigation, using people who impersonated military officers. In fact, I think there was more than one secret UFO investigation going on, and probably still is.
