That "rubber stamp" court at FISA was created in response to far worse breaches of power (and the law) by various LE agencies and NSA itself which were revealed in the late 1970s. The actions of an NSA trying to keep up with rapidly changing technology in a way that doesn't violate the law (even if only technically so) is a far cry from the abuses that led to the Church Committee.

So if this (like last time) is the low that we will improve from after the bright light of transparency was shined on the enterprise, then the U.S. will be in great shape.
