Just lovely. It appears that he was in counseling, and was briefly hospitalized, as a direct result of abusive FBI tactics, which included pressuring his children to turn on him, telling his son that he could get the $2.5 million dollar reward and buy a sports car, and showing his daughter gruesome pictures of the Anthrax victims, and told her, “Your father did this.”
The FBI has noted his access to a lyophilyser, a freeze drying maching that, “could be used to dry wet anthrax into powder,” but would not have produced weaponized anthrax.
The output would resemble instant coffee, which would require extensive processing to become inhalable. I used to do routing maintenance on an lyophilyser in an medical lab (1982-3), and I am aware of its capabilities.
A number of his co-workers believe that the FBI singled him out because of history of alcohol problems and other problems, so they figured that they could break him.
