Well, I wasn't going to reply until I had my own response completely fleshed-out and deemed substantial, but I haven't been able to really get the time to prepare an entire dissertation on the subject. In the meantime (and I may come back and put more of my own thoughts into it all), I'll just post this, because it does bring up a good number of the points I would have brought up:
276 Strange Coincidences about 9/11
Now, please bear in mind that I'm not calling this link a smoking gun, or even stating that all of these listed points are unequivocally true. They do, however, warrant further inquiry, in my opinion. I chose this particular list because it does try to at least site sources and references, which is something that so many other 'conspiracy theorist' postings neglect to do. So, do take each declaration as its own point, and not treat the whole thing as a 'conspiracy theorist's rant,' or cherry-pick a few falsifiable claims on the list, to try to discredit the entire list (not that you'd do that). Look into the statements individually and try to prove/disprove them, through any means available. I've been steadily trying to do the same, but there are a lot of these 'coincidences' that have been talked about, and I'm only one man. :chuckle:
Really, though...if these (or, even a majority of these) are actually true, that is an astoundingly high level of coincidence for an unprecedented attack that - allegedly - nobody had any prior knowledge of.
