Because the FBI went around seizing tons of footage and burying it.

There we a bunch of cameras on the roof and needle on top of WTC 1 and 2. They would've had the best view of the planes hitting the tower. But that footage has never been released. Odd. Just like they wont release the footage of a 747 striking the Pentagon, even though that building is surrounded by a ton of cameras too.
