TSA says Washington passenger didn't know about sword WASHINGTON, March 21 (UPI) -- The Transportation Security Administration said a woman didn't know her cane contained a sword until she went through an X-ray machine at a Washington airport. The TSA said the machine picked up something strange about the woman's cane Monday at Washington Dulles International Airport and officers discovered the knob unscrewed to reveal a sword, WUSA-TV, Washington, reported Thursday. TSA officials said the woman had purchased the cane at an antique store and was unaware of the concealed weapon. She was allowed to continue on to her flight -- without the cane.
