Mr. McCLOY. While we are waiting for Mr. Rankin to continue his examination, let me ask you this question, Chief. Did you, prior to the assassination, know or hear of Oswald? Mr. CURRY. Never. Mr. McCLOY. Didn't hear that he had been--there was a defector named Oswald in the city of Dallas? Mr. CURRY. No, sir. Mr. McCLOY. Never heard of his name? Mr. CURRY. We didn't have it in our files. Representative FORD. Was there anything in your files that Lee Harvey Oswald had been involved with the Dallas police force? Mr. CURRY. No, sir. Representative FORD. No record whatsoever? Mr. CURRY. No, sir. Mr. DULLES. Was there any record of his having made a trip to the Soviet Union and returned? Mr. CURRY. Not in our files. Mr. DULLES. And returned to Texas? Mr. CURRY. We didn't have anything in our files regarding Lee Harvey Oswald. Senator COOPER. Could I follow up on that, did you have any record of any individuals, persons, in Dallas, or the area, who because of any threats of violence against the President or any Communist background required you to take any special security measures? Mr. CURRY. Yes, sir; when we have notables, celebrities visiting us, there are some groups in Dallas that are known to be extreme rightwing and extreme leftwing groups. We try to keep track of these people and what their plans are. We have been able to infiltrate most of their organizations. Senator COOPER. Now prior to the President's visit, did you take any--did the Dallas Police force take any special security measures about any persons that you might suspect of possible violence? Mr. CURRY. Yes, sir; we kept some people under surveillance or groups under surveillance. We had prior to this visit, we had some information brought to us, I don't know who brought it to us, that there was a man in Sherman or Denison, who said that he is going to see that the President was embarrassed when he came to Dallas. Senator COOPER. Who was that man, do you know? Mr. DULLES. We have a Secret Service report, I believe with regard to this case. Here is one from the chief of police of Denton, Tex. Mr. CURRY. Yes; we had some information that the students at North Texas were planning some demonstrations. Senator COOPER. My question is, did your police force take any special security measures about anyone that you felt might be capable of violence against the President? Mr. CURRY. Not at this particular time, because we had reports from the different groups, and we had information from inside these groups that they were not planning to do anything on the day the President was there. We knew that General Walker was out of the city, and we knew that his group that sometimes put on demonstrations. Senator COOPER. When you say planning, you are not limiting it to any violence, but you are talking about any possible demonstrations? Mr. CURRY. Yes; demonstrations.
