I sincerely doubt the argument that dragnet surveillance has no effect. I wish as soon as the information could be de-classified the NSA would publish about attacks it stopped. Doing so can expose sources and methods used to collect the information, so not everything would become known - but it would certainly help to benefit the agency and its credibility in the eyes of the governed.
That said, I don't want to live in a country that looks over my shoulder as I grow and mature my reasoning about the world. We need the ability to formulate our own opinions without feeling watched (because this leads to self-censorship!). Discourse is necessary for society to evolve. We wouldn't have things like interracial marriage without people taking unpopular ideas to market.
I just wish we could see the full benefits of both sides in this argument.
