Mr. Curry. They usually have an informant inside the organization. Sometimes it may be one of our own men.
Mr. Rankin. I see.
That was with regard to the persons listed on that Exhibit 710?
Mr. Curry. Yes.
Mr. Rankin. Do you know of any other efforts besides that?
Mr. Curry. No, sir; these are all that I know of except we did in one instance go to the cities outside of Dallas, towns outside of Dallas to talk to some people that had rumored that they would do something to embarrass the President. These organizations are listed as the Ku Klux Klan, the Indignant White Citizens Council, National States Rights Party, the John Birch Society, Dallas White Citizens Council, Oak Cliff White Citizens Council, General Walker group, American Opinion Forum, Dallas Committee for Full Citizenship, Young Peoples Socialist League, Dallas Civil Liberties Union, Texas White Citizens Council, and Black Muslims.
Mr. Rankin. I will hand you Exhibit 709 which you have furnished us this morning, and ask you, can you tell us how you got that exhibit?
Mr. Curry. This exhibit was a report that was submitted to me from Jack Revill, who is a lieutenant, in the criminal intelligence section.
Mr. Rankin. That is the same man who is referred to in Exhibit 710?
Mr. Curry. Yes, it is; their assignment is to keep track of these groups that we have talked about, possible subversive or extremist groups and try to know something about their plans, their movements.
