themselves as to be deemed a potential danger to him. On November 8, 1963, after undertaking the responsibility for advance preparations for the visit to Dallas, Agent Lawson went to the PRS offices in Washington. A check of the geographic indexes there revealed no listing for any individual deemed to be a potential danger to the President in the territory of the Secret Service regional office which includes Dallas and Fort Worth.21

To supplement the PRS files, the Secret Service depends largely on local police departments and local offices of other Federal agencies which advise it of potential threats immediately before the visit of the President to their community. Upon his arrival in Dallas on November 12 Lawson conferred with the local police and the local office of the Federal Bureau of Investigation about potential dangers to the President. Although there was no mention in PRS files of the demonstration in Dallas against Ambassador Adlai Stevenson on October 24, 1963, Lawson inquired about the incident and obtained through the local police photographs of some of the persons involved.22 On November 22 a Secret Service agent stood at the entrance to the Trade Mart, where the President was scheduled to speak, with copies of these photographs. Dallas detectives in the lobby of the Trade Mart and in the luncheon area also had copies of these photographs. A number of people who resembled some of those in the photographs were placed under surveillance at the Trade Mart.25

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,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.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
