Salon.com News | Biological alarm in Washington: “Oct. 18, 2005 | WASHINGTON — On Sept. 24, 2005, tens of thousands of protesters marched past the White House and flooded the National Mall near 17th Street and Constitution Avenue. They had arrived from all over the country for a day of speeches and concerts to protest the war in Iraq. It may have been the biggest antiwar rally since Vietnam. A light rain fell early in the day and most of the afternoon was cool and overcast.
Unknown to the crowd, biological-weapons sensors, scattered for miles across Washington by the Department of Homeland Security, were quietly doing their work. The machines are designed to detect killer pathogens. Sometime between 10 a.m. on Sept. 24 and 10 a.m. on Sept. 25, six of those machines sucked in trace amounts of deadly bacteria called Francisella tularensis. The government fears it is one of six biological weapons most likely to be used against the United States.”
Scary article. It’s worth reading the whole thing.
