This evidence permits a more refined estimate of the perpetrator’s motives. He must be angry at some biodefense agency or component, and he is driven to demonstrate, in a spectacular way, his capabilities and the government’s inability to respond. He is cocksure that he can get away with it. Does he know something that he believes to be sufficiently damaging to the United States to make him untouchable by the FBI?

The perpetrator is surely too smart to believe that either the FBI’s ludicrous recent actions or the White House protestations of ignorance mean that the authorities are not on to him. Blanketing Central New Jersey with fliers showing handwriting that was obviously disguised can’t possibly evoke useful information, nor can letters to 32,000 American microbiologists, 31,800 of whom live in a different world from the perpetrator. This is no way to instill public confidence in the competence of the FBI. The press is increasingly questioning the situation, and other scientists have independently raised similar issues (see, for example, "In Search of the Anthrax Attacker" http://www.redflagsweekly.com/nassanthrax3.html). Most importantly, the apparent lack of action is sending a dangerous message to potential bioterrorists.
