There is a lot of good stuff on NSA spying on citizens, press, and political opponents, the technical issues, as well as legal and political aspects of it on the internets, but I wanted to put together links to some of the best. Many of those posts also link to other good bloggers' commentary as well, so follow the hyper-yellow-brick-road:
The first stop just has to be Gary Farber: See the most recent posts here, here, here, here, here, here and here. Once you're done with those, set aside a couple of hours and read this post and ALL of the links within it. Once you understand the technical and terminological issues, you will realize how REALLY eggregious abuse of civil rights the whole NSA spying thing is.
Will Raymond shows how the issue is reflected locally (in Orange County, NC, but it can be translated into any part of the country) and what you, as an individual, can do about it here, here, here, here, here and here.
Then, go and read Lindsay, who has some important thoughts on the topic here, here, here, here, here and here.
Amanda chimes in here and here.
Publius just started on this here and here, but promises more.
The crowd over on Shakepseare's Sister had some really good stuff, including on the non-involvement of cable-phone companies, for instance here, here, here, here, here, here and here.
Glenn Greenwald has wise words here, here, here, here and here.
Finally, what does Elizabeth Edwards think about her own phone being tapped? See here.
