Jeb! Bush thinks the NSA needs more power to spy on the average American, because _he_ hasn't found any evidence of civil liberty violations, so clearly we should extend powers until we do.
But, more importantly, without giving the NSA more power and eliminating public access to strong cryptography, "It makes it harder for the American government to do its job while protecting civil liberties to make sure evildoers aren't in our midst."
Dear, Jeb!, I hate to tell you, but evildoers are always in our midst. Sometimes they look like evil Muslim assassins or greasy Italian gangsters. Sometimes they look like business suited white guys. Sometimes they even look like whatever it is that NSA agents look like.
Assuming all of those people are "evildoers," and all of we people are good and kind and beneficent seems … shortsighted. Assuming that if we just make police and security forces more and more powerful then they will be able get rid of all "evildoers in our midst" is naive to the point of being disingenuous.
Jeb Bush: the NSA isn’t spying on us enough
Because “evildoers.”
