That’s not true there are no real secrets in Amerithrax. The name of the mailer has never been publicly mentioned in any context — such as a report of a search, a subpoena, etc.
Someone from the Army Chemical Corps was quoted in the press today about going into the Florida newspaper office:
It was pretty scary at first, to be honest; there was a lot of apprehension going in there, Corey said. We didnt know what we were getting into, nobody had ever done this before. It was a brand new experience and we didnt really have anybody to fall back upon to get good advice from.
The learning they did have — or the CDC would have had had they read the report in their inbox — involved testing done of mailed anthrax after the threat relating to the detention of Vanguards of Conquest #2 Mahmoud Mahjoub in late January 2001. It found that the anthrax immediately dispersed upon opening of the envelope and leaked before opening. US personnel separately were briefed on it months earlier before findings were formalized.
