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.
Don't overreact. Recall that the only source supporting this accusation is an unnamed "government official", as reported by Bob Woodward and published by the Washington Post.
I rather imagine that Bob Woodward and the Post are the ones "trying to blame innocent Americans". The FBI probably knows better...
