On the other thread, Fred Mertz pointed out that the local TV news programs mentioned that the cameras were already there when the vans arrived.
It was a staged event, not a serious investigation.
Exactly. A few months ago, the FBI leaked a story "on background" to ABC News about an ex-Battelle scientist who supposedly had made anthrax threats just after September 11. ABC used the story to pad out one of the boilerplate "domestic suspect" filler pieces that were coming out at that time. The outlines of the story sounded really impressive. However, even with the vague details they provided, there was enough in ABC News' story to dig up the one extant contemparaneous reference to the incident on the web, which appeared in a Milwaukee newspaper (I may have been the first person to that, incidentally). Within a couple of days it came out that the suspect was completely innocent and the whole story was nothing but a red herring.
Pay close attention, because the same patterns keep repeating themselves. Bush cannot point the finger at the source of the anthrax, because the anthrax threat is designed precisely to deter Bush from finger-pointing. Hence the stall. But here's a clue: the anthrax was supplied to the 9-11 team by Saddam Hussein, who is also the architect of the entire 9-11 operation. It's his "insurance policy."
