I just wanted to chum the waters for any passing conspiracy theorists in the area:
From this CNN article
Now from an article a week before the London bombings:
So it seems we had some people in government, and private sector, decrying the Patriot Act and not wanting to renew some of its more intrusvie powers. Then we have a London bombing, by London Nationals no less, and look…most of the Patriot Act provisions are now permenant, and others are extended years!!
