You are an apologist for an overreach of which you don't seem to fully comprehend or appreciate.
In the early days of these Snowden releases, Senator Nancy Pelosi represented your perspective. She downplayed the NSA programs saying there was full Congressional oversight and she had been aware of them through her briefings and they were ok.
Every week she was asked by reporters, "Did you know about such-and-such, and did you approve of it?" Early on she answered "Yes" to these queries. But somewhere along the way before it was revealed the NSA had tapped Angela Merkel's personal cellphone, Senator Pelosi realized there was a lot she didn't know about. The NSA had played her and her peers for fools. Now Senator Pelosi doesn't field those questions from reporters about oversight and what she had approved.
I predict as you learn more about the activities and programs of the NSA, you'll change your tune as well.
