They actually did a pretty good job given the situation, at least as far as what has been reported.
I'm far more worried about surveillance that is privatized. Examples are Fusion Centers and contracting out for trojans to companies in Europe.
On Fusion Centers:

These FC's have access to 240 state, regional, and federal agencies and their databases, including agricultural and parks agencies. FC's also monitor surveillance systems, intersections, thoroughfares, and parking lots across America. In Chicago, hi-tech infrared surveillance cameras, that store video feeds for more than a dozen years, are set up every mile along the Windy City's freeway system. One FC can access hundreds of private security cameras in railroad yards, trucking sites, sports arenas, office buildings, shopping malls, large retail stores, and warehouses.
On security companies spyware such as Finspy:
"The report also noted that one of six U.S. spy servers is registered to Verizon Wireless."

Who are these people? Who is in charge of oversight? If they have collected information on a citizen, how can that citizen find out since FOIA laws might not apply?
