If a terrorist wanted to launch a biological attack on the US they would be quite stupid to target a remote farm. Not too many people who will come into contact with it before the first victim is hospitalised and diagnosed. If this were a real attack they would instead have injected a few bumsters in a big city. No one cares about those anyway, so they can infect half the city without anyone noticing, and they won't make it to the hospital either, so by the time the first victim gets diagnosed it will be too late. Anthrax in the early stages could be treated right? Then why wouldn't they use CCFH instead, or ebola? Highly infective, always deadly, and not (easily) curable. Sure it shows itself earlier, but if you inject a few bums with that a whole city will be dead in a matter of days. There was an outbreak of CCFH at the border of Afghanistan, so you can be sure they have that at least, even if they don't have ebola.
