You could be right, but it may be that the Feds just aren't sure whether the Shaikh brothers and Kazi are involved or not. They may not have information that would let them bring charges; there may just be a lingering suspicion of involvement, well covered up.
It's also quite possible that the government just doesn't want to take any action now, even if they know the truth, because they are unwilling to deal with the military consequences at this time. This is more than just a criminal case. (If we were ready to go to war with Iraq, or Iran, or whoever they hypothetically might know is behind the anthrax attack, then we'd already be at war. We're biding our time, waiting for the right moment. And we're not going to be forced into taking military action prematurely by the exigencies of a criminal case or its political fallout.)
On Allah Rakah, I presume we'll find out the truth some day. I suppose someone could file a FOIA request on Rakah's status, if the government starts really pushing the Rosenberg theory or the like.
Precisely my view.
"if the government starts really pushing the Rosenberg theory or the like."
Rosenberg's "source", she says, is an "insider", in the government. So, I assume it the government that is already pushing the Rosenberg theory. Which is, I'm guessing, misdirection -- for the very reason discussed above.
The more one noodles this whole chain of events around in the mind, the more likely it is that the anthrax came from Iraq. Or Iran. Or North Korea...
When all the laundry is hung out on the line, the left is going to be very disappointed...
