Mr. Dulles. Is there any practice of going to the superintendent of a building and putting any responsibility on him to see that strangers don't come into the building at that time, or assuming any responsibility at all with respect to the inmates of the building? I don't know what the practices are.

Mr. Lawson. As I stated, sir, there was for inaugurations here in Washington—we have done building surveys of buildings that overlook the White House, that overlook the grounds, that overlook areas where the President goes quite often or where he might be out or something like that. Yes, sir; we keep those quite up to date. Out on a trip away from Washington, I have never requested building superintendents to do this. This was not the usual practice.

Mr. Smith. May I ask a question there, sir. Is any of that information that you just gave the type of thing that is not supposed to be known publicly? I just don't know how necessary this is to the record, I mean about checking the buildings around the White House and so on. Is there anything about that that is sensitive?

Mr. Lawson. I would assume that most of the people thought that we did.

Representative Ford. I think that is the general impression.

Mr. Lawson. Yes, sir.

Mr. Smith. I can check on that. If there is something in there I might want to come back on.

Representative Ford. I think as far as we are concerned if you do check on it and find that it is something that ought to be left off the record we could certainly do so.

Mr. Dulles. It might be declassified as a whole or lower the classification, so I think it is well to put in the record what you have said, that this part of the record should be reviewed by the Secret Service, and if it is a security matter I think they ought to raise it. I don't think we want to ever disclose anything that the responsible agency thinks would imperil the life of any President.

Mr. Smith. I have in mind what he said and I will check on it right away. Unless I come back and make some point about it, why you can rest assured that there will be no problem.
