No, they are taking it because they work in a maximum-risk location which now has one confirmed instance of multiple exposures. This is the same thing they did for the people in Boca and NBC. The feds are not prohibiting medication in cases of high risk or possible exposure. They are recommending against premedication (which is detrimental) and against any widespread stockpiling that would make an effective response to a massive attack impossible.
Remember that the terrorist's main goal in this psychological war is to turn us against each other and against our country, to dimish our ability to act. Don't let them do this tou you, and don't be a tool to facilitate this. Like it or not - by events not of our choosing - we are all combatants now.
Er, widespread stockpiling is clearly a necessary preparation for an effective response to a massive attack.
Ah, the voice of reason. Well said, sanchmo.
If you can keep your head while all about you are losing theirs...
