I noticed this in an article about how increased security and a general risk aversion is harming US diplomatic missions:
"Barbara Bodine, who was the U.S. ambassador to Yemen during the Qaeda bombing of the U.S.S. Cole in 2000, told me she believes that much of the security American diplomats are forced to travel with is counterproductive. "There's this idea that if we just throw more security guys at the problem, it will go away," she said. "These huge convoys they force you to travel in, with a bristling personal security detail, give you the illusion of security, not real security. They just draw a lot of attention and make you a target. It's better to fly under the radar."
It's a good article overall.
