The National Security Agency went all out on a Christmas gift this year: a decade's worth of declassified documents on the unauthorized surveillance of Americans.

Turns out it's the NSA that sees you when you're sleeping, and knows when you're awake.

The documents were released Wednesday afternoon, in response to an ACLU lawsuit under the Freedom of Information Act. They cover the agency's activities from mid-2001 through early 2013 — and they are heavily redacted.

Even so, the reports detail numerous "errors" over the years as NSA analysts searched through its information databases and accessed the communications of Americans, which is prohibited.

“The vast majority of compliance incidents involve unintentional technical or human error,” the NSA said in the executive summary. "These materials show, over a sustained period of time, the depth and rigor of NSA’s commitment to compliance."

"NSA goes to great lengths to ensure compliance with the Constitution, laws and regulations.”

Indeed, much of the reports detail things like accidental queries on the wrong "targets," or overly broad searches that reveal a lack of proper training for analysts. However, some of the errors were intentional.

In 2012, for example, an NSA analyst searched "her spouse’s personal telephone directory without his knowledge to obtain names and telephone numbers for targeting."

Documents leaked by Edward Snowden have already revealed that the NSA has violated privacy rules thousands of times each year. The agency also admitted last year that in "very rare instances" its analysts willfully violated the rules — such as an analyst tracking a former spouse. The reports released Wednesday had been sent quarterly to the President’s Intelligence Oversight Board and the Office of the Director of National Intelligence. Because of the redactions, it's not clear how much new light they will shed on the NSA's overreaches.

If you are interested in reading through the reports, it is helpful to understand a few terms that are used so often one hopes they are all banned in 2015. Among them:

target: the individual the agency intended to surveil

selector: information identifying an individual or household, such as a set of IP addresses

task/detask: to begin or end surveillance on a selector

NSA Intelligence Oversight Board Report, October-December 2012

Many of the reports begin with the same message to the chairman of the Intelligence Oversight Board, stating:

"Except as previously reported to you or the President, or otherwise stated in the enclosure, we have no reason to believe that intelligence activities of the National Security Agency ... were unlawful."

Or: We don't think we did anything wrong when we weren't doing the stuff that was wrong.

With the redactions, it is difficult to tell exactly how sensitive information was when it was accessed "in error."

Patrick C. Toomey, a staff attorney with the ACLU's National Security Project, said the documents show that more oversight of the NSA's activities is needed.

“The government conducts sweeping surveillance under this authority — surveillance that increasingly puts Americans’ data in the hands of the NSA,” he told Bloomberg, which first reported the new documents. “Despite that fact, this spying is conducted almost entirely in secret and without legislative or judicial oversight."
