This is scary.  Especially the fact that it took some time for the other agents to notice something was awry (Note: San Francisco uses a private screening agency).
This takes place in San Francisco Airport.
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.
Each woman left the room not exhibiting apparent signs of distress. But an actual screener thought that something was wrong. Only female officers are supposed to accompany women sent into the private room for extra screening, which can include a full-body pat-down. And blue shirt and gloves notwithstanding, the man had no badge or emblem on his shirt, clearly not a screening officer.
Read the New York Times for more details.
The police have decided not to prosecute.
