Today, it's hard even to recall just how terrifying those anthrax attacks were. According to a LexisNexis search, between Oct. 4 and Dec. 4, 2001, 389 stories appeared in the New York Times with "anthrax" in the headline. In that same period, 238 such stories appeared in the Washington Post. That's the news equivalent of an unending, high-pitched scream of horror – and from those attacks would emerge an American world of hysteria involving orange alerts and duct tape, smallpox vaccinations, and finally a war, lest any of this stuff, or anything faintly like it, fall into the hands of terrorists.
And yet, by the end of 2001, it had become clear that, despite the accompanying letters, the anthrax in those envelopes was from a domestically produced strain. It was neither from the backlands of Afghanistan nor from Baghdad, but – almost certainly – from our own military bio-weapons labs. At that point, the anthrax killings essentially vanished… poof!
