The Bill of Rights Defense Committee has put together a 26-minute video entitled “FBI Unbound: How National Security Letters Violate Our Privacy”, which can be viewed online or ordered on DVD. It features interviews with Lisa Graves, Bruce Fein, and George Christian, who actually received one of these letters and can talk about it.
Cyberlaw Central Commentary:
National Security Letters are the hidden, secret ways that ISP’s can be ordered to turn over customer information without judicial oversight. Authorized by the Patriot Act, these are intended for anti-terrorism activities, but are capable of significant abuse. This video does a good job explaining what they are, I highly recommend watching.
