There was mention that Fort Detrick is a place where they have anthrax, and they use it in tests.
They also noted that all the anthrax researchers live in the area.
If someone called this a "raid", then they have never seen a real raid. This was a consensual search. The doctor let the FBI in! They took some stuff out to study at leisure.
Or is there some other news story concerning Fort Detrick that we should pay attention to?
According to CNN and NBC
there have been dozens of such searches.
Nothing suspicious has been found.
