Since all this ancient anthrax discussion is being regurgitated once again
perhaps I should stress once more
that producing and handling highly aerosolized 1 trillion spores per gram powdered anthrax
that floated like smoke
would necessarily require the use of a BL4 lab.
To quote
Wikipedia:
Biosafety Level 4
This level is required for work with dangerous and exotic agents
that pose a high individual risk of aerosol-transmitted laboratory infections.
(btw
this is a good, interesting article
with a list of BL4 labs in the USA and outside.)
Did Ivins have access to a BL4 lab?
If so
how could he have used it
without attracting the attention of dozens of his co-workers?
More interesting question:
Could anthrax of this quality have been made
in any BL4 lab
whose existence was not secret??
