The fact that the Patriot Act was drafted quickly proves that there is a security establishment, waiting to pounce on opportunity. It doesn't prove that 9-11 was somehow caused by such a group.
The first half year later they had a thorough analysis of each executive order.
Soon so many executive orders, each more disturbing than the last, were being signed that they gave up analyzing them completley and just had quick summaries.
Then soon they couldn't keep up and just listed them with links to info obtained by freedom of information orders.
In 2004, they were "executive ordering" at the rate of about 30,000 new pieces of "emergency legislation" per year and the site just shut down, unable to keep up.
NOW YOU JUST KNOW that dude from Texas isn't penning 30,000 pieces of legislation per year. Heck - with all the vacationing, it's a wonder he even gets to sign it all.
Seems like you're right - all these things were prepared way in advance, just waiting for an opportunity.
