The National Security Agency may present a united front when it defends against criticism of its bulk phone data collection, but it's now clear that there has been at least some doubt within the ranks. Associated Press sources have revealed that there was an internal proposal to kill the phone surveillance program in early 2013, not long before Edward Snowden's leaks made it public. Reportedly, some NSA officials were concerned that the initiative was not only expensive to run, but ineffective. It wasn't "central" to catching terrorist plots, and it wasn't capturing most cellphone calls. Not surprisingly, the critics were also worried about outrage if the truth came out -- which, of course, is exactly what happened.
