Firstly, does he seriously believe that, or are you just demonizing him because it'll get you agreement? If he said something to that effect, that's concerning, but if he hasn't, can we stick to things which have actually happened?

And secondly, is not the motivation to stop terrorists in the US from harming US citizens a noble goal, in theory? Now granted, we shouldn't have to sacrifice our privacy to get that done, but it's not like Keith Alexander is trying to harm the US. He wants to help, and depending on who you ask, may be misguided, on the money, or completely wrong in how he plans to help.

It'd be more useful to correct than to abolish, because abolishment of the NSA and it's surveillance programs is never, ever going to happen, nor should it. ZERO surveillance (this might be arguable, I suppose) results in US citizens dead on US soil. Unacceptable.
