"Evidence?"
If the sequence of events as speculated about turns out to be true, what kind of evidence would be available?!
Would you dismiss a connection as unreal until an FBI agent just happens to walk into a two bedroom apartment where, in one bedroom, a guy is mixing up anthrax and in the other a guy is typing up computer code?
I mean, this is 2001. People doing this kind of terrorism aren't idiots. This weird, constant talk of "evidence" has an air of insanity to it.
More likely than not, there will NEVER be evidence that will stand up in a court of law EXPLAINING everything nice and tidy. But so what? Law enforcement or intelligent agencies still have to respond sooner rather than later to this kind of large scale threats. They have to act on something other than "court room evidence." And if we're going to understand what's going on around us, we have to recognize that although "evidence" is great and although it's dangerous to speculate without hard, material evidence, there are many situations where people just have to get creative, people have to trust their judgement, and people have to deal with conclusions based on them being persuasively true rather than true beyond a shadow of a doubt.
Reality is not a court room. It's just not. There is a kind of insanity in trying to deny all of reality that doesn't meet those utterly artificial standards.
