6 years after 9/11 there have been no terror attacks here in the United States.
I've long been fascinated by the erasure of the anthrax attacks - which, in their own way, freaked out the country more than 9/11 did* - from our collective memory.
*People object when I suggest this, but while the 9/11 attacks were of course The Big Ones, anthrax was this creepy shit which was KILLING US THROUGH THE MAIL. While most people didn't expect a plane to fly into their building, the anthrax attacks created a heightened sense of OMIGOD THIS COULD HAPPEN TO ME. 9/11 was terrible, but the anthrax attacks were terrifying to people.
