I'm Bill Binney, former NSA Tech Director. Worked for NSA 37 years. I know that you can have your liberty W/O sacrificing security! AMA.
In the late 90's I co-created the program "ThinThread" which was the perfect alternative to mass surveillance - but it was ditched by NSA for money.
ThinThread was a fully automated system that could monitor signals then filter and alert on genuine threats in near real time. It did this all whilst protecting citizens rights to privacy. Its efficacy was down to its being metadata focused.
See more about the film of ThinThread's story and my career here. Currently screening in CPH:DOX Copenhagen and will screen in NYC on the 15th Nov. http://agoodamerican.org/
