According to Agent Rowley's 13 page memo to FBI Director Robert Mueller, Dave Frasca threw "up roadblocks and undermined Minneapolis' by now desperate efforts to obtain a FISA search warrant, long after the French Intelligence service provided information and probable cause became clear." (Rowley's memo to FBI, May 21, 2002, page 3) (see the following web site)
http://www.time.com/time/covers/1101020603/memo.html Not only did Dave Frasca not share the information about Moussaoui to other appropriate intelligence/law enforcement authorities, he also, according to Rowley "never disclosed to the Minneapolis agents that the Phoenix Division had, only three weeks earlier, warned of Al Qaeda operatives in flight schools seeking flight training for terrorists purposes!" (Rowley's memo to FBI, May 21, 2002 p. 3) It is of course impossible to believe that Dave Frasca on his own, is just sitting on this information and not doing anything with it, unless ordered to do so.
The Minneapolis agents even tried to do an end run around Dave Frasca and notified the CIA's Counter Terrorist Center. The end result was that FBI headquarters personal (Dave Frasca and unnamed higher ups) "actually chastised the Minneapolis agents for making the direct notification without their approval." (Rowley Report, p. 4) Going even further, Dave Frasca "undercut" the search warrant application by not adding information on Moussaoui's foreign power connections which he had promised Minneapolis agents would be included. He also made damaging changes to the text provided by Minneapolis agents thereby, according to one Minneapolis agent, "setting this up for failure." (Rowley Report p. 4)
Even after the World Trade Center was hit, Agent Rowley asked Dave Frasca if she could now obtain a criminal search warrant for Moussaoui's laptop and personal property, she was again refused because it was probably all a "coincidence". Agent Rowley was warned to "do nothing" because "we might ‘screw up' something else going on elsewhere in the country." (Rowley Report, p. 7) The words "do nothing" are interesting; even more revealing what's to ‘screw up' at that point, except another plane going into another building?
After, when Rowley talked to other FBI agents in other parts of the country, the first question was Why?—"Why would an FBI agent(s) deliberately sabotage a case?" Agent Rowley reports that jokes were made that FBI Headquarters personnel were "spies" or "moles" who were actually "working for Osama Bin Laden." (Rowley Report p. 7) Apparently no one mentioned that it could be the other way around i.e., Bin Laden working for the CIA/FBI. The notion that Bush cabinet members were urging the CIA/FBI chiefs to keep a lit on local FBI investigative actions to arrest or curtail terrorist plots was, at the time, an unthinkable thought. That after all, would not be a joke. It would be one of the most murderous, diabolical cover up committed against American citizens by an American President and cabinet.
