Everyone is FISA-eligible: "which may include American citizens and permanent residents suspected of being engaged in espionage and violating U.S. law on territory under United States control" - http://en.wikipedia.org/wiki/Foreign_Intelligence_Surveillance_Act http://en.wikipedia.org/wiki/Foreign_Intelligence_Surveillan..., paraphrasing http://www.law.cornell.edu/uscode/text/50/1801 http://www.law.cornell.edu/uscode/text/50/1801 (b)(2)(C). Certainly it makes sense for the NSA to store all communications by FISA-eligible persons, if they can. With the Bluffdale datacenter, storing connection information becomes feasible. I worry about the interpretation of the FISA law where potentially anyone is FISA-eligible. Do you have reason to believe that the NSA would reject that interpretation? More fundamentally, is it acceptable for lawmakers to pass FISA in its current form if it allows that interpretation? If so, what would make the law unacceptable?
