Here's the condescending generic email response I got from @SenFeinstein (NSA)

7. Feinstein's statement is full of hogwash.

To take the most egregious example, Feinstein's email says

First, I understand your concerns and want to point out that by law, the government cannot listen to an American's telephone calls or read their emails without a court warrant issued upon a showing of probable cause.

This is false. The government can examine the contents of phone calls or emails of people it thinks are foreigners with 51% certainty. If it turns out the people involved are Americans, it can still keep that data if they think it fits any of several categories. No warrant is needed for this.

Don't even get me started on the idea that metadata is somehow benign or that Congress really knew what was going on. Ugh.
