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.
Mr. STERN. But he would, as I understand it, sir, be included in the
basic files if he had come to their attention as a potential danger.
Mr. DULLES. Someone in New Orleans, for example, he could get up to
Dallas very quickly or if he were in Houston, but this 50,000 covers
the whole world.
Mr. STERN. Yes; and I think the important point here, Mr. Dulles, is
that these are 50,000 cases of background information, including people
already investigated and found not to represent danger. The number of
cases under active scrutiny at the time of Dallas amounted to about
400, who were reviewed periodically, plus a much larger number, in
the thousands, of persons committed or imprisoned, and as to those, I
expect there would be no problem until they were released.
Mr. BOUCK. That is right.
Mr. STERN. And you had a system to be notified about the release or
escape, is that correct?
Mr. BOUCK. That is correct.
Mr. DULLES. So can we get from that about the number of cases you felt
to look at in connection with the President's trip to Dallas?
