William Binney is one example of a mathematician working at the NSA (building Stellar Wind) who has spoken at length about this: http://www.nytimes.com/video/opinion/100000001733041/the-program.html http://www.nytimes.com/video/opinion/100000001733041/the-pro... http://www.democracynow.org/2012/4/20/exclusive_national_security_agency_whistleblower_william http://www.democracynow.org/2012/4/20/exclusive_national_sec...
