Note this paragraph from the article:
"Some bioweapons, including anthrax spores, can contain chemical additives to permit the germs to float freely in the air. Experts who have seen the mailed anthrax have been divided on what additive it contained or whether it contained one at all."
The chemicals found are the key to finding out where the anthrax came from. For some reason the FBI are denying these chemicals exist - even although government labs have conformaed they are there.
The 2 chemicals are silica and an exotic siloxane binder. This recipe comes straight out of the cookbook of the nation that developed the weaponization method.
See http://anthrax2001.blogspot.com for more details.
I don't know why they are witholding the information but they must have a very good reason.
Weren't they using submicron bentonite, too? This is not surprising though because silica (Cab-O-Sil) and silane couplers. etc. are commonly known and used in many fields. Tens of thousands of people in food, drug, coatings, and polymer fields must know that. Cab-O-Sil N70TS is even supplied with a silicone coating.
It's about time he updated that site !
What cookbook are you referring to?
Or do you just mean that if we knew that some nation had used this weaponization method, then that nation, or somebody with access to their program, would be the prime suspect?
Interesting....
