Terrorists? Or our own government?

I'll bet you didn't hear about this:

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.

It was an alarming reading. The biological-weapons detection system in Washington had never set off any alarms before. There are more than 150 sensors spread across 30 of the most populated cities in America. But this was the first time that six sensors in any one place had detected a toxin at the same time. The sensors are also located miles from one another, suggesting that the pathogen was airborne and probably not limited to a local environmental source.

William Stanhope, associate director for special projects at the St. Louis University School of Public Health's Institute for Biosecurity, has been closely following scattered government and news reports about the incident. He's convinced it was a botched terrorist attack. "I think we were lucky and the terrorists were not good," he says. "I am stunned that this has not been more of a story."

The DHS scrambled for three days to confirm just what may have been in the air that day. On Sept. 27, it turned for help to the Centers for Disease Control and Prevention. The CDC did its own tests, and on Sept. 30 -- six days after the deadly pathogens set off the sensors and well into the incubation period for tularemia -- alerted public health officials across the country to be on the lookout for tularemia, the deadly disease caused by F. tularensis.

"It is alarming that health officials ... were only notified six days after the bacteria was first detected," House Government Reform chairman Tom Davis, R-Va., wrote in an Oct. 3 letter to Homeland Security Secretary Michael Chertoff. "Have DHS and CDC analysts been able to determine if the pathogen detected was naturally occurring or the result of a terrorist attack?"

Government officials say the sensors detected a natural event. "There is no known nexus to terror or criminal behavior," Russ Knocke, spokesman for the Department of Homeland Security, told the Washington Post. "We believe this to be environmental." "It is not unreasonable that this is a natural occurrence," says Von Roebuck, spokesman for the CDC. "There are still no cases of tularemia."

However, Salon has spoken to numerous people who were at the Washington Mall on Sept. 24. Four say they got sick days later with symptoms that mirror tularemia.

There was another troubling thing. One of the sensors that went off was located at the Lincoln Memorial on the far western end of the Mall. Another was located near Judiciary Square, roughly two miles to the east and two blocks north of the Mall. A third was at the Army's Fort McNair, more than two miles from the Lincoln Memorial down the Potomac River past the Mall, on the point of land where the Washington Channel and Anacostia River meet. The locations of the other three sensors have not been disclosed.

This makes a natural event on Sept. 24 more difficult to imagine. Under the government's scenario, soil on or near the Mall somehow became contaminated with the bacteria, perhaps from the body or blood of a dead or injured small rabbit or squirrel. That soil then got stirred up -- possibly by the marchers themselves -- and floated across the Mall and beyond. Marchers and book festival attendees contacted by Salon say it was dusty on the Mall in the morning. But it rained early that day and stayed moist, making the dust theory perhaps less likely, at least after that rain.

"One sensor, I'd say maybe," says biosecurity expert Stanhope of the dust theory. "Two sensors is a stretch. Six sensors? I'm sorry, you don't have enough money to buy enough martinis to make me believe that it is naturally occurring at six different sites. I don't think you could get me that drunk to believe that."

As for how the bacteria may have erupted through natural processes, says Hinrichs of the University of Nebraska Center, "I can't imagine how it could have happened." Asked if he could imagine a scenario whereby F. tularensis could float around the Mall in the dust, Bender, an infectious disease epidemiologist, says, "Theoretically, it is possible." Asked if it could have been an attack, he says, "The question you are asking, 'Was this real or not?' That is a very valid question."

More.... (get the day pass if you don't subscribe to Salon)

Now why on earth would terrorists target an antiwar march? It just doesn't make sense, does it? On the other hand, it DOES make sense that our own government, headed by people who wish that antiwar activists would just go away, might decide to do some biological weapons testing in the middle of a peace march, doesn't it?

In this case, as far as I'm concerned, Occam's Razor leads us AWAY from the terrorist theory, AWAY from the "naturally occurring pathogen" theory, and leaves us with a government attack on peace marchers in the guise of a weapons test.
