It actually would be better for the apologists to come out and say that you want the government to have carte blanche access to all of our information. At least it's honest and doesn't waste people's time in these trivial non-debates about peripheral non-issues.

OTOH, of course, that posture is all the more stupefying. Which "truth", exactly, is so important that we should all be willing to give up our privacy?

And, how is it that you find it so easy to trust our government with such power? After all, if it is untoward human beings who make truth-finding so difficult that these drastic, privacy-defiling measures are necessary, then why do you have so much trust for other fallible human beings to wield this power?

It doesn't matter which truth exactly. The more information they have access to, the better the decisions they will be able to make (in theory, at least).

I don't trust them to wield that power because I don't need to trust them. I hope that by wielding that power, they destroy it by making it clear to the world that privacy no longer exists.
