Here is a very interesting article by Susan Landau.

Her thesis is that the actions taken by the Bush administration and our state security apparatus have the effect of making us more vulnerable to spying and cyberterrorism.

Her very valid point is that the surveillance society envisioned by Bush and His Evil Minions^™ will require a back door on every phone switch in the country, and once there, it will be significantly easier for state and non state actors to hack into the switches and listen to our communications.
