The Anthrax attacks were almost certainly connected to Sep. 11
Although the letters with anthrax weren't mailed out until the day after the Sep. 11 attacks, they obviously couldn't have been prepared overnight. What are the chances that a domestic lone wolf American scientist just happened to be working on the first bioterrorism attack in American history at the exact same time that Al Queda terrorists were planning and executing the Sep. 11th attacks, and that he just happened to have everything ready to go mere hours after hearing about the Sep. 11th attacks?? It's not plausible.
