If this passes, the problem will be catching the NSA at their dirty activities. To do this, Arizona will have to develop NSA-like surveillance that is almost as good as that of the NSA. When that happens, what's to keep Arizona from turning their own intel-gathering capabilities on Arizona citizens and the rest of the world? Nobody but the Arizona surveillance team will know if they are following orders that forbids them from observing citizens and joining the NSA, because they will be the only ones with this kind of technology in Arizona. Kind of a potential catch-22 for Arizonans.
