If anything, the Anthrax was mailed to liberals to gin up support for the Patriot Act, etc.
Speaking of the beltway snipers. Why hasnt't AQ copied that MO? Two men effectively terrorized and shut down DC/NVA area.
No movie plot needed for the terrorist, just use guns to snipe people. Pretty, effective for AQ or any other Terror organization to do.
Don’t forget the BTWC, though. Both Drs. Hatfill and Ivins were against it, I believe.
