Four years ago today, the first batch of anthrax letters was postmarked.

The fact that the investigation has produced no arrests is even more depressing than the failure to capture Osama bin Laden. The anthrax guy's probably still running around the United States somewhere. If the top-notch officials in "Homeland Security" haven't figured it out yet, it seems unlikely that they ever will.

Maybe it's the local officials' fault.

Besides destabilizing the world, which we're quite good at, do we ever achieve what we set out to do any more?
