I would hate to reduce it to binary but things like installation of proxy hardware (Blue Coat[1]) to monitor with or court orders for conscription of local hardware are. Without people collaborating along with the US government, then people... wouldn't be collaborating. Those within the USG would be forced towards alternative routes such as those detailed in the PRISM slides.
Bonus: Security creates insecurity, all this logging and data collection creates more data. This data, which Snowden's Booz Allen Hamilton has shown[2], can be leaked. As an example a look into the Blue Coat logs leaked[3] from Assad's Syria by extraordinary esoteric activists Telecomix[4] reveals followers of Christianity along with homosexuals intently monitored.
Bonus Caution: I wouldn't touch the Booz or HBGary leaks unless you like federal prosecution for assisting in dissemination of data on the profiteering collaborators[5].
