With skepticism from key members of Congress and acquaintances of the late Bruce Ivins about his possible role in the anthrax mailings of 2001, the pressure is growing on the FBI to disclose its evidence, the New York Times reports. In executing the probe, the Times says the FBI helped invent what was virtually a new science, microbial forensics, the use of biochemical clues to track a germ weapon to its source. As the investigation wore on, some colleagues termed the FBI's methods increasingly coercive, as the agency tried to turn Army scientists against one another and reinterviewed family members.
FBI officials say they do know a great deal about what happened and will make it public, possibly as early as tomorrow. They say the core of their case will be the science, which produced the giant step from a globe of possible suspects to a single lab and a single flask.
