I've always said the anthrax was radical left wing anti-capitalist taking advantage of Pig Ladins hit and run.
It's always been my opinion.
Hope they catch these crazy left wing zealots.
"Mother earth" wouldn't be there to defend them!
When asking who would benifet most from the attacks, the answer is always the left wing terrorist groups , politicians, and their other socialist cronies.
'Domestic' anthrax was probably stolen by foreign students from University and Government labs who use these students as a cheap labor pool. They are the ones with the most probable access and the most likely motivation.
