The FBI office in Dallas gave the local Secret Service representatives the name of a possibly dangerous individual in the Dallas area who was investigated. It also advised the Secret Service of the circulation on November 21 of a handbill sharply critical of President Kennedy,[C2-24] discussed in chapter VI of this report. Shortly before, the Dallas police had reported to the Secret Service that the handbill had appeared on the streets of Dallas. Neither the Dallas police nor the FBI had yet learned the source of the handbill.[C2-25] No one else was identified to the Secret Service through local inquiry as potentially dangerous, nor did PRS develop any additional information between November 12, when Lawson left Washington, and November 22. The adequacy of the intelligence system maintained by the Secret Service at the time of the assassination, including a detailed description of the available data on Lee Harvey Oswald and the reasons why his name had not been furnished to the Secret Service, is discussed in chapter VIII. The Luncheon Site An important purpose of the President’s visit to Dallas was to speak at a luncheon given by business and civic leaders. The White House staff informed the Secret Service that the President would arrive and depart from Dallas’ Love Field; that a motorcade through the downtown area of Dallas to the luncheon site should be arranged; and that following the luncheon the President would return to the airport by the most direct route. Accordingly, it was important to determine the luncheon site as quickly as possible, so that security could be established at the site and the motorcade route selected. On November 4, Gerald A. Behn, agent in charge of the White House detail, asked Sorrels to examine three potential sites for the luncheon.[C2-26] One building, Market Hall, was unavailable for November 22. The second, the Women’s Building at the State Fair Grounds, was a one-story building with few entrances and easy to make secure, but it lacked necessary food-handling facilities and had certain unattractive features, including a low ceiling with exposed conduits and beams. The third possibility, the Trade Mart, a handsome new building with all the necessary facilities, presented security problems. It had numerous entrances, several tiers of balconies surrounding the central court where the luncheon would be held, and several catwalks crossing the court at each level. On November 4, Sorrels told Behn he believed security difficulties at the Trade Mart could be overcome by special precautions.[C2-27] Lawson also evaluated the security hazards at the Trade Mart on November 13.[C2-28] Kenneth O’Donnell made the final decision to hold the luncheon at the Trade Mart; Behn so notified Lawson on November 14.[C2-29]
