Re: Speculation of Attack Prior to Sept.11,2001
I wouldn't attach too much significance to it. There is such a broad spectrum of discussion going on on the internet that it would be surprising if almost any form of terrorist or shocking act had not been discussed sometime. If you want to prove this, run similar searches for anthrax in the mail, or destroying dams, or any other conceivable attack.
Heck, we talk about dropping asteroids on things here.
