Report Rebuts Bush on Spying

From today's Washington Post: Report Rebuts Bush on Spying -- Congressional Research Service takes a look at the legal arguments to date and concludes that there's a problem with the unsanctioned surveillance of US residents communicating electronically with those overseas.

I'm not sure that my proposal goes far enough to protect against this kind of abuse, though the existence of clear Congressional instructions for this exceptional use of executive power is arguably enough.  What happens, however, when we learn that purely domestic communications have also been intercepted and scanned and evaluated?  Is the grand high poobah of law-and-economics, Richard Posner, right when he writes or chats that collection, compilation, and filtering of electronic communications is completely legit?  (Stay tuned for further discussions on that one...)
