Mr. THORNLEY. Well, that meant in a practical sense, that meant that he was not permitted to enter certain areas wherein the equipment, in this case equipment, was kept; that we would not want other unauthorized persons to have knowledge of. And on occasion information, I imagine, would also come to the man who was cleared, in the process of his work, that he would be expected to keep to himself. Mr. JENNER. I assume you had clearance? Mr. THORNLEY. Yes, sir; I was, I think, cleared for confidential at the time. Mr. JENNER. Cleared for confidential. I was about to ask you what level of clearance was involved. Mr. THORNLEY. I believe it was just confidential to work there at El Toro on that particular equipment. Mr. JENNER. That is the clearance about which you speak when you talk about Oswald having lost it? Mr. THORNLEY. Oswald, I believe, had a higher clearance. This is also just based upon rumor. I believe he at one time worked in the security files, it is the S & C files, somewhere either at LTA or at El Toro. Mr. JENNER. Did you ever work in the security files? Mr. THORNLEY. No, sir. Mr. JENNER. And that was a level of clearance---- Mr. THORNLEY. Probably a secret clearance would be required. Mr. JENNER. It was at least higher than the clearance about which you first spoke? Mr. THORNLEY. Yes, sir. Mr. JENNER. The clearance that you had in mind of which you first spoke was the clearance to operate radar detection devices? Mr. THORNLEY. Right. Mr. JENNER. And your knowledge of his loss of clearance was by hearsay or rumor. As I understand it the circumstances took place off base one day? Mr. THORNLEY. No; this was on base as I understand it. It was in an enlisted club or staff sergeant's club, something of that nature. Mr. JENNER. He had gotten into difficulty with a staff sergeant and had poured beer on the person of a staff sergeant and gotten into some kind of an altercation? Mr. THORNLEY. Yes, sir. Mr. JENNER. As a result of that he was court-martialed and had been subjected to the loss of clearance? Mr. THORNLEY. That is correct. Mr. JENNER. Was that clearance of his restored? Mr. THORNLEY. I doubt it very much, because 3 months afterwards, after I had left the outfit--I know it wasn't restored while I was in the outfit. Mr. JENNER. When did you leave the outfit? Mr. THORNLEY. I left in June and went overseas. Mr. JENNER. Up to that time his clearance had not been restored? Mr. THORNLEY. Definitely not. And shortly thereafter he got out of the service. Mr. JENNER. So that as far as you have any personal knowledge Oswald never operated any radar equipment while he was at El Toro, did you say? Mr. THORNLEY. Yes; El Toro, LTA. As far as my personal knowledge goes, he didn't.
