History

Historical Context

September 2001, a week after the 9/11 attacks, anthrax spores mailed to media outlets and Senators Tom Daschle and Patrick Leahy killed five people and infected dozens, spurring a nationwide overhaul of bio-hazard protocols and the launch of the BioWatch early-warning system. The June 11 2026 Pentagon Force Protection Agency shelter-in-place drill, with Arlington HazMat teams responding, shows the enduring inter-agency coordination born from those attacks.
