@Walter Hinteler,
There are three main issues for me beyond the fact that this program exists at all, which is the greatest issue, imo.
The other three bugs in my craw are:
a) there is no evidence that metadata collection resulted in the prevention of a single event that wasn't prevented by other, more tradition, means.
b) the idea that there is congressional oversight of this program is clearly bogus. The heads of the committees in both houses of congress should be thoroughly investigated for dereliction of duty.
c) another reason stated in the declassified FISA rulings was that Congress reauthorized the program in 2011 with full knowledge of the entire voting body. THIS IS FALSE! Mike Rogers, chair of the House oversight committee chose not show the DOJ report that detailed metadata collection to the full House. No one from the class of 2010 ever saw the report unless they were on the Intelligence Committee. I can't tell you what his reasoning was, but for FISA to now say that it's ok because it was reauthorized by full disclosure of the program to everyone in Congress is bullshit.
