On a Tuesday morning in September 2001, the American experience with terrorism was fundamentally altered. Two thousand, nine hundred and ninety-six people were killed as the direct result of attacks in New York, Washington, D.C., and Pennsylvania. Thousands more, including many first responders, later lost their lives to health complications from working at or being near Ground Zero.
Nineteen years later, Americans’ ideas of what terrorism is remain tied to that morning.
