see url: http://en.wikipedia.org/wiki/ThinThread As promised...here is my posting on thinthread and Trailblazer.Thinthread as the name implies tried to gather the minimum of information required for National Security purposes, it had controls on it which limited unneccessary spying, violating as few citizen rights as possible. Whereas, Traiblazer had no such considerations and acted as a carpet sweeper.
Remember Obama's 3 hops argument...and his reducing it to 2? Well, that is what it was all about...Trailblazer gathered everything. There was so much stuff tha the NSA computers and storage facilities couldn't handle all of it. There was no time to sift and sort through it, heirarchisize it, prioritise it...so everything got collected...including information on American citizens...which is against the US Constitution, apparently. Well, at least to Diane Roark and most other people in the world, but not to the NSA...All part of their "exceptional" but legitimate "activities"...:-)
For the rest of the 6 billion 700 million, people on the planet, those considerations did not and do not apply.
Enjoy. ATB Sweep.P.S. All that Diane Roark wants is to get her private stuff, back, her computers and emails...and give back to the NSA any classified material which she may inadvertently hold. It is taking an awful long time...and all those personal attacks, villifications and accusations of being unpatriotic...after all, she did the right thing, she approached the right people...one wonders why, she is being subjected to such mistreatment by the worlds greatest example of democracy and preserver, advocate and exporter of human rights and civil liberties...
