We will remember the 2,977 people from more than 90 nations who were killed as a result of the horrific terrorist attacks on September 11, 2001. More than 400 of them were people who responded first to the attacks.
The easiest reaction is to just pick a side. Either the 9/11 hijackers were normal, or they were insane. Ten years after that day, this false dichotomy continues to distort explanations of why the U.S. was attacked.
