Unless someone can prove that no one involved in the tuskegee "incident"[0] is no longer employed or influential at the CDC I will just resign myself to thinking that THEY are the conspiracy theorist, a conspiracy to seem infallible or at least incorruptible. Such a concept is of course ridiculous, don't turn off your brain with an appeal to authority.
