Dear Mr. D: AT&T has a long history of vigorously protecting customer privacy. Our customers expect, deserve and receive nothing less than our fullest commitment to their privacy. We also have an obligation to assist law enforcement and other government agencies responsible for protecting the public welfare, whether it be an individual or the security interests of the entire nation. We prize the trust our customers place in us. If and when AT&T is asked to help, we do so strictly within the law and under the most stringent conditions. Beyond that, we don't comment on matters of national security....
