The same emails reached school districts across the country. In NYC, officials viewed them as part of a never-ending stream of obvious hoaxes. Across the country (and a lot closer the most recent terrorist attack), LA officials took the emails seriously enough to close schools for the day. From WaPo: “The two cities’ divergent choices, made in the face of similar threats, are a sign of the murky calculus that government officials face as they try to protect the public without giving in to the fear terrorists seek to cultivate.” I sure wouldn’t want to have to make that call.
