All of the spying didn't stop the Boston bombings, so I find the excuse of "terrorism" to be flimsy, at best, and the citation of the "3rd party doctrine" fails

All of the spying didn't stop the Boston bombings, so I find the excuse of "terrorism" to be flimsy, at best, and the citation of the "3rd party doctrine" fails to consider that when we, as Americans, post letters through the USPS, we have a "reasonable expectation of privacy" as pertains to our personal correspondence. Our correspondences, be they electronic, or otherwise, equate to "papers and effects," in that "papers and effects" were the communications media of the founding father's era. That the present administration has chosen to continue these unconstitutional practices when we are obviously not happy about it is more in keeping with Communist China, and NOT what we would expect from "the Land of the Free."
