Spokesperson Paul Bresson announces that the FBI has concluded that there was no insider trading in US securities markets by people with advance knowledge of the 9/11 attacks. According to Bresson, the “vast majority” of a pre-attack surge of trading in options that bet on a drop in the stock of AMR Corp., which owns American Airlines, and UAL Corp., which owns United Airlines, was conducted by investment hedge funds implementing bearish investment strategies or hedging a line position of common stock, and was not linked to terrorists.

May 2007 – November 26, 2007: Unfounded Warning of Terrorist and Drug Cartel Attack on Arizona Army Base
An FBI advisory is distributed in May 2007 to the Defense Intelligence Agency, the CIA, Customs and Border Protection, and the Justice Department, as well as numerous law enforcement agencies throughout the nation warning that up to 60 Afghan and Iraqi terrorists are to be smuggled into the US through underground tunnels with high-powered weapons to attack an Arizona Army base. The alleged target, Fort Huachuca, is the nation’s largest intelligence-training center. It lies about 20 miles from the Mexican border and has members of all four service branches training in intelligence and secret operations. Security measures are swiftly changed at the base in response to the threat, according to multiple confidential law enforcement documents obtained by The Washington Times. The advisory warns that “a portion of the operatives were in the United States, with the remainder not yet in the United States [and]…the Afghanis and Iraqis shaved their beards so as not to appear to be Middle Easterners.” The FBI report on which the advisory is based points to the involvement of Mexican drug cartels, stating that each operative paid drug lords $20,000 “or the equivalent in weapons” for assistance in smuggling them and their weapons , including anti-tank missiles and surface-to-air missiles, through tunnels along the border into the US. The advisory further warns that a number of the operatives are already in a safe house in Texas and some weapons have already been successfully smuggled into the US. The FBI report is based on Drug Enforcement Administration sources, including Mexican nationals with access to a “sub-source” in the drug cartels. This “sub-source” is allegedly “a member of the Zetas,” the military arm of one of Mexico’s most dangerous drug-trafficking organizations, the Gulf Cartel, who identified the Sinaloa cartel as the organization involved in the plot. However, the advisory states that “this information is of unknown reliability,” while the DEA warns that the Gulf Cartel may be attempting to manipulate the US into acting against their rivals. FBI spokesman Paul Bresson says that the report is based on “raw, uncorroborated information that has not been completely vetted.” A Department of Homeland Security document on the possible attack states “based upon the information provided by the DEA handling agent, the DEA has classified the source as credible [and]…the identity of the sub-source has been established; however, none of the information provided by the sub-source in the past has been corroborated.” [Washington Times, 11/26/2007] The threat later proves to be unfounded. The attack never occurs and FBI spokesman Manuel Johnson, based in Phoenix, admits in November that the warning was the result of bad information. He says “a thorough investigation was conducted and there is no evidence showing that the threat was credible.” [Arizona Daily Star, 11/26/2007]
