Mr. McCONE. That is quite correct; there is no question about that. Representative FORD. And I am only suggesting that if the regulations were not adequate at the time and are not now, maybe something ought to be done about it. Mr. RANKIN. Mr. McCone, when you said that supplying all of the information about U.S. citizens who went abroad and came back to the country would not be a profitable exercise, did that comment include the thought that such an intrusion upon all citizens would be questionable? Mr. McCONE. Such an intrusion? Mr. RANKIN. Upon their right to travel. Mr. McCONE. Well, I think this would have a bearing on it. I did not have that particular matter in mind when I made that statement, however. I was just thinking of the---- Mr. RANKIN. Burden? Mr. McCONE. Of the burden of vast numbers involved. Mr. RANKIN. Do you you have any thought in regard to whether it would be an intrusion upon their rights? Mr. McCONE. Well, that would be a matter of how it was handled. Certainly, if it was handled in a way that the counterpart of providing the information was to impose restrictions on them, then it would be an intrusion on their rights. Mr. RANKIN. Yes. Senator COOPER. May I inquire? The CHAIRMAN. Senator Cooper. Senator COOPER. I missed the first part of Mr. McCone's testimony; I went to answer a quorum call. Perhaps the question has been asked. It has been brought into evidence that a number of people in the Embassy talked to Oswald when he first defected, and the various communications with the Embassy and, of course, when he left to come back to the United States. Have we been able to ascertain the names of officials in the Embassy or employees with whom Oswald talked on these various occasions? Mr. McCONE. I am not familiar with them; no. Mr. HELMS. Neither am I, sir. Mr. McCONE. I presume that the Department's inquiries have covered it. Senator COOPER. Is it possible to ascertain the names of those employees? Mr. RANKIN. Senator Cooper, I can answer that. We have inquired of the State Department for that information, and are in the process of obtaining it all. Senator COOPER. Taking into consideration your answers to the previous question, would it have been possible in your judgment to have secured more comprehensive information about the activities of Oswald in Russia? Mr. McCONE. It would not have been possible for the Central Intelligence Agency to have secured such information because we do not have the resources to gain such information. The CHAIRMAN. Anything more? Congressman Ford? Representative FORD. Did the Central Intelligence Agency investigate any aspects of Oswald's trip to Mexico? Mr. McCONE. Yes; we did. Representative FORD. Can you give us any information on that?
