This is more likely to have been caused, by harsh chemicals use in decontamination.
I have yet to see any heads roll for the intelligence failures of 911. And the obvious incompetence of the FBI, in every aspect of the Anthrax attack, demands some accountability. These Bozos, seem to think gathering evidence, and gaining more invasive powers, is more important, than protecting US citizens.
Except, they aren't really looking for and gathering more evidence. They are trying to blame innocent Americans for the anthrax attacks, without any evidence at all.
Maybe Bush and those high mucky muck politicians don't really know what the FBI is like and what the common person thinks of the FBI. Maybe we should be writing them, telling them. I know the crooked pols probably have the FBI and other government agencies looking out for them but there has to be a few good, honest pols in Washington or we're up a creek without a paddle.
