Two identical dates, plus similarity of method and purpose. How much more evidence could there be at this stage? It merits further investigation.similarity of method, i.e. meaning they are both "mail" (snail and "e") ... Yes, and ???? Does that mean that anyone that ever drove a truck has something in common with anyone else that drove a truck? especially if they did it on the same day? ... these "connections" are weaker than weak!!
Purpose?-That's redundant to "method" ... i.e. if your purpose is to get information channels blocked, you would in effect use the information channel to do the blocking. No, this is a great model for conspiracy chasers only.
Date- I have already stated that the ONLY thing going here is the similarity of dates ... but what is that? nothing.
SANTA and SATAN have the same letters, just rearranged ... heck that's got as much "conspiracy" grounding in it as this does.
Who would have thought that there were Japanese spying all over numerous countries in the late 30's and early 40's, collaborating with Nazi's to boot --including a certain chap who lived for awhile in Pearl Harbor and liked to watch the ships move in and out of port?
Unlike the run-of-the-mill conspiracy theory, this ones has testable conclusions; it's falsifiable. If it's correct, there ought to have been anthrax mailings postmarked very close to Oct. 12 and Oct. 29. (Even if such mailings turn up, I would agree that that's not definitive proof. If no such mailings turn up, however, that would be a strong argument against the theory.)
By the way, the similarity of method is much more than the fact that both used mail. Both involve using mail to send unrelated destructive payloads to unsuspecting people. (This may still not be enough to satisfy your standards for a connection, but it is more of a connection than your characterization suggests.)
Also, the similarity of purpose isn't the same as that of method. People have suggested lots of other possible rationales behind the anthrax attack (a warning from Iraq, for instance, or bin Laden aiming at the media to elicit maximum hysteria as he tries to goad us into an attack on all of the Muslim world, or possibly a test of how a biological agent would spread in the mail, or other possibilities). If this connection is true, it suggests a particular specific purpose, namely trying to disrupt or even shut down our mail and other communication systems.
Anyway, since the theory has testable conclusions, I thought it would be of interest to get it out there now, rather than after any further mailings are discovered (since at that time, people might say that the theory was tailored to fit the facts). Time will tell if it is true or false.
