Put another way, I want them to follow the damn law rather than deciding they can make up the law and do whatever they want.
If there is no process to determine whether the lines they are listening to really belong to 'suspected terrorists,' you have no idea whether this is what they are doing or not.
I believe in our Constitution and our laws, and they have gotten us through times far more dire than these. It is when we toss them aside that we are truly imperiled.
No. No discernment resides within the agency responsible to track terrorists. Just judges have it...unelected judges. Somehow, unelected judges know how to protect our liberties. Gee, I must have missed that in my Gestapo 101 class.
