The Secret Service is concerned that President Bush might be the target of a terrorist attack while he is being driven to Sarasota-Bradenton International Airport and provides extensive security to protect him during the journey. [LBJ Presidential Library, 9/3/2013; Politico Magazine, 9/9/2016] Bush and his entourage left the Emma E. Booker Elementary School in Sarasota, Florida, at around 9:35 a.m. to be driven to the airport, where Air Force One is waiting (see (9:34 a.m.) September 11, 2001). [Daily Telegraph, 12/16/2001; 9/11 Commission, 7/24/2004, pp. 39] Bush’s Secret Service agents have arranged extensive security measures to protect the motorcade during the journey. Dave Wilkinson, assistant special agent in charge of the presidential protection division, will later describe: “We asked for double-motorcade blocks at the intersection. Double and triple blocks. Not just motorcycle officers standing there with their arms up, but vehicles actually blocking the road.” [Politico Magazine, 9/9/2016] Additionally, the vehicles in the motorcade are driven at around twice the normal speed, going at 80 to 85 miles per hour instead of the usual 40 to 45 miles per hour. [LBJ Presidential Library, 9/3/2013] Furthermore, Secret Service agents in the motorcade “all had weapon barrels that were visible and they were pointing up at the ready position in case they needed to be used,” according to Officer Kevin Dowd of the Sarasota Police Department. [BBC, 9/1/2002] The Secret Service is specifically worried that a suicide bomber might be nearby and try to crash a truck bomb or a car bomb into Bush’s limousine. Edward Marinzel, the head of Bush’s Secret Service detail, has therefore arranged for the Sarasota Police Department to mobilize every available patrol car and, as it travels to the airport, the limousine is surrounded on all sides by these cars. The hope is that they will block any suicide attack on the vehicle, should one be attempted. [Rove, 2010, pp. 251; LBJ Presidential Library, 9/3/2013] The Secret Service is also “using the limos [in the motorcade] as a shell game, to keep the president safe” during the journey, Wilkinson will say.
