Mr. Bouck. Yes; I think——
Mr. Stern. As a matter of fact, I would suppose the people in the album would also be in the checkup control file so really we are talking about, are we not, the unknown number in institutions, and about 400 other individuals whom you were actively reviewing and about whom you would be concerned on the occasion of the President's trip?
Mr. Bouck. That is right.
Mr. Stern. In addition, you had files on, active files on, approximately 50,000 cases involving at least that number and probably more, individuals which were your basic library, as it were, but of reference use only until more information was developed about them?
Mr. Bouck. Well, I think you are quite accurate except in the last category. In these 50,000 cases would be tremendous numbers of cases that had been given investigative attention, and had been determined that our first thought or our first indications of danger were not substantiated. The investigator, and we concurred, felt that the individual, at least at any particular time, that this particular individual was not really in fact a menace to the President's life.
Mr. Dulles. What was the location of these 50,000 cases? We are talking now about Dallas, is that countrywide?
Mr. Bouck. Countrywide.
Mr. McCloy. International.
Mr. Bouck. It is worldwide over a period of 20 years.
Mr. Dulles. Yes. Somebody in Thailand, if he was in Thailand wouldn't be of much danger in Dallas.
