Beyond the AT&T incident (and following legal ruling dismissing, retroactively, carriers from wrongdoing in wiretapping).... there's also the 'TrailBlazer Project'[1] with public accounts from William Binney (NSA , 'Director of World Geopolitical and Military Analysis Reporting Group')and Thomas Drake [2] (NSA) regarding the overreach of such projects....that it's kinda hard to exclude data and so forth.
Jacob Applebaum (Tor, etc) recently dragged William Binney around NYC to gather publicity [3] - but few outlets paid much attention.
