National security protocols dictate that when a weapon of mass destruction is located the FBI takes lead, coordinating with local agencies, which in this case involved the Defense Department, Port of Anchorage, Department of Energy, and Anchorage Police.Though Alaska is not considered a high-risk target, ports across the country have been consistently criticized for their vulnerability to attack. As of 2012, only 4.1 percent of the 11.5 million containers shipped into U.S. ports were screened, according to Bloomberg News. The Port of Anchorage handled 1,9511,820 tons of freight in 2014, constituting about 90 percent of all the cargo brought into Alaska.Feger-Pellessier couldn not say how much the exercise cost.
