Here is another monkey wrench - The CDC is thought of as a civilian agency, but unbeknownst to most -- virtually all of the major policy and professional appointments at the CDC are staffed by MILITARY officers. This is described in the official gov't handbook on U.S. federal agencies. If you want a copy I can send it to you.
Funny, on other threads you seem to put a lot of faith in the FDA. Pretty selective if you ask me. Is your faith agenda driven? Just curious.
