Former TSA chief backs 'knife' decision; suggests axes and machetes, too - CNN.com

Washington (CNN) -- The former head of transportation security said Wednesday he supports a new policy allowing small knives on planes, but said it does not go far enough, and should include instruments such as "battle axes (and) machetes."

Sharp objects can no longer bring down aircraft, former Transportation Security Administration chief Kip Hawley told CNN, and the search for knives interferes with the search for objects that can harm aircraft.
