"Since 9/11, we've spent hundreds of billions of dollars defending ourselves from terrorist attacks. Stories about the ineffectiveness of many of these security measures are common, but less so are discussions of why they are so ineffective. In short: Much of our country's counterterrorism security spending is not designed to protect us from the terrorists, but instead to protect our public officials from criticism when another attack occurs.
Boston, Jan. 31: As part of a guerilla marketing campaign, a series of amateur-looking blinking signs depicting characters in Aqua Teen Hunger Force, a show on the Cartoon Network, were placed on bridges, near a medical center, underneath an interstate highway and in other crowded public places.
Police mistook these signs for bombs and shut down parts of the city, eventually spending more than $1 million sorting it out. Authorities blasted the stunt as a terrorist hoax, while others ridiculed the Boston authorities for overreacting. Almost no one looked beyond the finger pointing and jeering to discuss exactly why the Boston authorities overreacted so badly. They overreacted because the signs were weird.
If someone left a backpack full of explosives in a crowded movie theater, or detonated a truck bomb in the middle of a tunnel, no one would demand to know why the police hadn't noticed it beforehand. But if a weird device with blinking lights and wires turned out to be a bomb -- what every movie bomb looks like -- there would be inquiries and demands for resignations. It took the police two weeks to notice the Mooninite blinkies, but once they did, they overreacted because their jobs were at stake.
This is Cover Your Ass security, and unfortunately it's very common."O artigo completo na Wired ou na Cryptogram.
