The Bushies see national disasters as opportunities to advance their own political agendas with reduced interference.
When 9/11 happened, they were actually caught kind of off guard. While it remains obvious (in spite of their suppressing the investigation of 9/11) that they knew something VERY bad was coming, they did not know just how bad it would be. When it happened, they rushed a lot of VERY questionable legislation through the Congress, but it was kind of half-baked stuff. Yes, they had been quite seriously mulling some of this evil stuff over, but the drafts had been going nowhere and fast. Even a few of their Republican congressmen were insufficiently reliable to ram this stuff through--until 9/11 happened, when they suddenly found they had carte blanche. Lots of the legislation had no legitimate relationship to national security, but they were quite happy to tie it to the big, strong coat tails of "anti-terrorism" and drag it along for the ride.
Now they are getting some really draconian stuff all written up and waiting, and if the opportunity presents itself, they'll be READY to capitalize on it. Not very funny, but I'm reminded of Bullwinkle Moose saying "This time for sure" about pulling the rabbit out of the hat. Usually he pulled out some sort of monster, and this new Patriot II will be pretty monstrous, but sometimes he pulled out Rocky, and that makes me think of each of us, John Q. Public, dangling helplessly in the government's newly iron-clad fist.
"Next time for sure!"
