It appears that the NSA has extremely sophisticated technology that can sift out and identify suspicious patters of telephone calls from the millions (billions?) of calls placed in the U.S. This could be a tremendous tool for thwarting terrorist plans.
Therefore, it seems perfectly sensible that some Americans are demanding that the program be scrapped and the data destroyed. Why stop there? Perhaps we ought to dismantle the NSA completely? That way, when some of us are blown to smithereens or killed slowly with biological or chemical agents, those who were not targeted can bask in the glow of knowing that their privacy was protected.
