The shiny new methods of "microbial forensics," touted by the FBI for months as offering a new break in the case, have in fact revealed little or nothing. As the New York Times' Scott Shane and Eric Lichtblau reveal, "officials admitted that more than 100 people had access to the supply of anthrax that matched the powder in the letters."
But the same article notes that FBI conclusively decided Hatfill had no access to the letters' anthrax, even though he was working at Fort Detrick during the time this strain of anthrax was stored there. If the FBI conclusively decided this (though the evidence appears weak), why haven't they provided Hatfill with a full exoneration? The FBI's logic is incomprehensible. I am not trying to finger Hatfill, who I believe is innocent. Just trying to understand the FBI.
