Mr. Stern. At the time of Dallas, do you know approximately how many persons were in institutions under this system where you would be notified if they left or escaped?
Mr. Bouck. I am sorry, I don't have that.
Mr. Stern. The order of magnitude, any estimate?
Mr. Bouck. It would be some thousands but I wouldn't really have a close idea. I could get that and supply it. I just would have to guess and it would be a very bad guess.
Mr. Stern. Fine. But you can determine this for us?
Mr. Bouck. Yes.
Mr. Stern. Good. How many at the time of Dallas would be in your checkup control file system with this periodic review?
Mr. Bouck. About 400.
Mr. Stern. 400 individuals?
Mr. Bouck. That is nationwide.
