Their name is the National Security Agency, after all. It seems that they should be focused on the security of all Americans, and rather than notifying and helping secure Americans they do the exact opposite. Is there another division in the government that reduces or allows the security of Americans to be so blatantly abused? If the military had just given away the keys to our nukes, Someone's head would roll, but because this is tech, and congress only sees a black box, they can't see that the NSA is more often acting against Americans' best interests rather than for.
