30. Anthrax Attack on US Government Employees, 2001: 5 Casualties, 17 Injured
While the nation was still reeling from the attacks of September 11, the threat of a massive anthrax attack shook people to the core. The scare began when people working in the US government buildings in Washington, DC, opened envelopes and were greeted with a white powder, which contained anthrax.
The FBI filed charges against Dr. Bruce Ivins in 2008, but he took his own life. In what became the worst biological attack on US territory, not least because of the terror that it inspired, five people died, and 17 people were injured. There are still theories that the government itself planned the attack as a scarecrow.
