Perhaps. Was it refined Anthrax of just cultures.
From what I've read the Anthrax powder that was mailed was highly refined and so called "weapon grade" anthrax, different from lab cultures etc.
But I'm no expert. Making highly refined anthrax is very difficult from what I've read. Requires very specialized labs.
Actually, that would hijack this thread.
I didn't want to do that.
But it is more of a simple answer of what type. There were labs and scientists involved IN the NJ area.
Alamo Girl has a thread up.
