The NSA makes thousands of screw-ups per year, it seems. Some of the transgressions were a bit more serious though.
The documents are a May 2012 audit that the NSA performed on its operations. Most of the privacy violations were unintended and resulted from things like typographical errors by analysts and programming errors. Some were much more serious, including one that involved unauthorized use of data on more than 3,000 US citizens. [emphasis added]
I’m glad we’re at least finally getting some transparency–if indeed that is what we’re getting.
Correction, this audit was one of the leaked documents, not one sanctioned for public release. I.e., this revelation wasn’t one of transparency, but a gift from Mr Snowden.
