On that Washington Post project (before having completed reading it, however):
I don't think the growth of the Intelligence apparatus is, on its own, outrageous.
In fact, I think strengthening of the Intelligence and law enforcement apparatus is the proper response to international terrorism. That is to say, if you had this growth of "Top Secret America" without the costly wars of Iraq and Afghanistan, I don't think there would be room for alarm or bitching.
The wars were the wrong response to terrorism, intelligence is the right one. Of course, it being America, it's still prone to go overboard even with the right response.
