Mr. Stern. Is there any other control device that you employed at the time of Dallas?
Mr. Bouck. We had at the time a very small device that we call an album which has a few, perhaps 12 or 15 people that we consider very dangerous or at least dangerous and so mobile that we can't be sure where they might be. This is a constant thing. Copies of these are kept before the protective personnel at the White House all the time. This resides in their office.
Senator Cooper. On that point, if this last category represents a group that is so highly dangerous, have any individuals in that group reached the place where they have made such statements as would bring them under the Federal act which would require prosecution?
Mr. Bouck. No, sir; if they were prosecutable we would seek that solution immediately, and many of them have been taken to the district attorney and it has just been determined they do not quite meet the requirements for prosecution.
Some have been prosecuted, and have served sentences and are out at the end of sentences but still thought to be dangerous.
Senator Cooper. Yes.
Mr. Bouck. Some have been in mental institutions and discharged, and there isn't ground to put them back but we are still afraid of them.
Mr. Stern. Are the individuals who are listed in the trip-index file, which numbered at the time of Dallas about 100, also listed in the checkup control files?
Mr. Bouck. Yes. Yes; they would, primarily that 100 would to a large degree be in both places.
Mr. Stern. Then it is a fair summary, Mr. Bouck, that at the time of Dallas the number of individuals that you were concerned with were some thousands, the number you will supply, who were institutionalized either in prison or in mental hospitals, and with such institutions you had an arrangement that would promptly notify you of the discharge or escape of that individual, some 400 on a systematic review, approximately every 6 months by your field offices, of which 400, 100 were separately identified as particularly dangerous in the trip-index file, and some 12 to 15 whose photographs were in the album?
