The man wearing a blue shirt and khaki pants stood casually inside a security screening area at a San Francisco airport terminal. As security officers and passengers bustled, he pointed to a woman and took her into the private screening room. Later, he pointed to another woman, and she followed him in as well.
The man, despite also wearing the blue latex gloves used by screeners, was no professional officer, said John S. Pistole, the administrator of the Transportation Security Administration. He was just another passenger with an international ticket.
Mr. Pistole described the encounters for me based on the surveillance video from the international terminal at San Francisco International Airport. Around noon on July 15, the man acted “like a security officer,” Mr. Pistole said, directing two women into the private area for extra screening, for about a minute at a time.
