Thanks for the links. I honestly have trouble remembering all the revelations at this point, given how many there have been!

However, those links still seem to imply that the NSA does not store the content of domestic phone calls. My point simply was that I believe the law is still crystal clear that the warantless collection and storage of the content of American's phone calls is unconstitutional, just as it would be illegal to x-ray the contents of letters. I can't imagine any court disagreeing. The fact that "metadata" on either may be legal under the third party doctrine or based on "reasonable expectations of privacy" is much less clear due to prior precedent, although I certainly agree with you that it should not be.

(Of course we also now know that the NSA has not been forthright about what they actually do, or what protections are in place to ensure that they can distinguish between domestic and international content. Indeed, it appears that with Internet content there is woefully deficient controls to ensure that domestic content is not stored. There is also another way they constantly chip away at privacy: arguing that there is not a 4th amendment issue until the content is searched, not merely indiscriminately stored.)
