This covers what I see as one of the biggest reasons for stopping the collection: It simply does not work. We are "winning" the war on terror just like we are "winning" the war on drugs in that we aren't making a dent at all and some argue that our actions in both fields actually spur on the exact activities they are meant to curb/destroy.

Don't get me wrong, I don't trust them with the data in the first place but even if I did it's been proven again and again that our privacy is being invaded and no positives are coming out of it. The NSA would have a much stronger position if it was "Yes, you have no privacy but there is also no terror" instead we have no privacy and terror attacks abound.
