I posted this a couple of breads back, but I don't think many paid attention.

This is a very recent (as in the last week) discussion with both Bill Binney and Thomas Drake and a couple others intimately involved in NSA. They cover NSA programs and the lead up to 9/11 and beyond.

Includes a video of the entire discussion, which runs just short of 2 hours. One of the points made towards the end reveals that the programs the NSA developed in-house were handed over to Israelis BEFORE 9/11, and shortly thereafter those programs were developed into commercial packages and sold back to the NSA for an inflated price.

Lots of other good info in here, worth listening to in the background.
