The National Security Agency has rejected a request to tell the public if they are violating our privacy, because it would violate our privacy to do so:

"Senator Ron Wyden has released some updated responsesfrom our national intelligence bosses concerning the questions that Wyden (and a few other Senators) have been asking for years. It's been pretty clear that a "secret" interpretation under the FISA Amendments Act (related to the Patriot Act) has meant that the NSA is scooping up tons of American communications, even as its mandate is that it only cover foreign intelligence—and Wyden has been pushing for more information."
