Like they did in the Boston bombings? Or 9-11? Or at Sandy Hook? Or what about Dorner? The problem is not only that it violates our rights, it also is a failure! They are either too busy spying on the wrong folks or the so called intelligent community isn't competent enough to handle a program so widespread! They can't spy on everyone! It will never work! They will miss the forest for the trees!
Behold, I send you forth as sheep in the midst of wolves: be ye therefore wise as serpents, and harmless as doves. - Matthew 10:16
