In no particular order:
The South Tower could (theoretically) have gotten near Wall Street as it fell (but didn't in actual fact). The North Tower couldn't, because it was too far away.
The Bin Laden "confession" tape was made by one of his (several) doubles. What does this have to do with anything?
If the core was destroyed by the upper stories crashing down, then what's this?

The resemblence to the lower half of the South Tower's core is amazing. And it doesn't appear to have been destroyed by the 50+ stories that hit it, although videos show that it starts to go right after this photo was taken.
