if they worked for the government, either they did it on their own to test the Anthrax or scare people into giving more fund to antibiotic research, or they just plain went crazy and spread the sh*t out to see what happens? Either that or one of the government workers is selling Anthrax to terrorist groups?

If the "Officials" gave orders to spread the Anthrax, you know that those orders would be shreaded by now. Blame it on an ex-government employee or something to sweep it under the rug.
