Nice work. A hospital lab would not likely be adequate to safely handle anthrax in quantity or otherwise grow, harvest, lyophilize, etc., though.....

Thank you so much, tracer! For reasons you've noted, we've been thinking that the perp was working with biologicals already prepared and provided to him. All he had to do was dish it out into envelopes as safely as possible. The different grades of anthrax speaks to this possibility.
