Once the Trade Mart had been selected, Sorrels and Lawson worked out detailed arrangements for security at the building. In addition to the preventive measures already mentioned, they provided for controlling access to the building, closing off and policing areas around it, securing the roof and insuring the presence of numerous police officers inside and around the building. Ultimately more than 200 law enforcement officers, mainly Dallas police but including 8 Secret Service agents, were deployed in and around the Trade Mart.[C2-30] The Motorcade Route On November 8, when Lawson was briefed on the itinerary for the trip to Dallas, he was told that 45 minutes had been allotted for a motorcade procession from Love Field to the luncheon site.[C2-31] Lawson was not specifically instructed to select the parade route, but he understood that this was one of his functions.[C2-32] Even before the Trade Mart had been definitely selected, Lawson and Sorrels began to consider the best motorcade route from Love Field to the Trade Mart. On November 14, Lawson and Sorrels attended a meeting at Love Field and on their return to Dallas drove over the route which Sorrels believed best suited for the proposed motorcade.[C2-33] This route, eventually selected for the motorcade from the airport to the Trade Mart, measured 10 miles and could be driven easily within the allotted 45 minutes.[C2-34] From Love Field the route passed through a portion of suburban Dallas, through the downtown area along Main Street and then to the Trade Mart via Stemmons Freeway. For the President’s return to Love Field following the luncheon, the agents selected the most direct route, which was approximately 4 miles.[C2-35] After the selection of the Trade Mart as the luncheon site, Lawson and Sorrels met with Dallas Chief of Police Jesse E. Curry, Assistant Chief Charles Batchelor, Deputy Chief N. T. Fisher, and several other command officers to discuss details of the motorcade and possible routes.[C2-36] The route was further reviewed by Lawson and Sorrels with Assistant Chief Batchelor and members of the local host committee on November 15. The police officials agreed that the route recommended by Sorrels was the proper one and did not express a belief that any other route might be better.[C2-37] On November 18, Sorrels and Lawson drove over the selected route with Batchelor and other police officers, verifying that it could be traversed within 45 minutes. Representatives of the local host committee and the White House staff were advised by the Secret Service of the actual route on the afternoon of November 18.[C2-38]
