Who did 9/11? The Iran contra players in coordination with SAIC, NSA under Hayden, Lockheed, Titan, Booz-Allen-Hamilton, Allied Signal, Raytheon, CSC, Mantech, Affiliated Computer Services ... the contractors who profited by the transfer of government functions to the private sector. That's who. They all had a hand in it.
