Mr. CURRY. It lies west of Dallas proper and across the Trinity River and the only means of going to Oak Cliff, going to and from Oak Cliff is by means of viaduct so there is a physical separation between Oak Cliff and Dallas, and some of the squads had been pulled out of the Oak Cliff area and to come over to the Elm and Houston area to assist in the investigation of this shooting, and it would be normal procedure as squads go out of an area for the squads further out to move in in the event something does happen in this area they would have a squad that wouldn't be so far removed from it. Mr. DULLES. This direction had nothing to do with any suspicion that you might have had that the assassin might be going into this area? Mr. CURRY. No, sir; none at all. Mr. DULLES. It was purely a maneuver to cover an area which had been evacuated or been left uncovered because of the assassination and the reassignment of squads? Mr. CURRY. The reassignment of squads, that is right. Mr. McCLOY. Because of the withdrawal of people of the Oak Cliff area into the Houston Street area? Mr. CURRY. That is correct. So we pulled some of the squads further assigned to the area into the most central area to cover anything that might happen so they would be in position to go out or come in. Mr. McCLOY. That does clear it up. Mr. RANKIN. Will you tell us on the record what was normal procedure that you just spoke about? Mr. CURRY. Normal procedure would be when we have a great number of squads on assignment in an area, in their particular district, as squads go out of service, say they are checking out, to haul prisoners into the jails or they are on calls, it just is automatic they are instructed in school when they go to school if the adjoining squad goes out of service, doesn't stay, say he adjoins you on the east, don't go to the far west side of your district, go to the east side of your district where you could be on the west side of his district, so if something else occurs in his district you would be in a position to answer the call. Ordinarily it is not necessary for us to, so that squads go to getting out of service, to go and rearrange squads. In this particular instance, when he asked 81 and 78 if they were in central Oak Cliff they said yes, but they were moving there because this would be a normal thing to do, to move into an area where other squads had gone out of service. Mr. RANKIN. You told us about your efforts to try to determine whether subversive groups or groups that might have an interest in making trouble for a trip of the President were going to try to do anything. Would you tell us what you did about that in more detail? Mr. CURRY. I gave you a copy of this, and I would like to read it for the record, if you would like me to. Mr. RANKIN. We will offer that. Mr. CURRY. All right. This is a copy of a report submitted to me by Lieutenant Jack Revill, criminal intelligence section of the special service bureau.
