The second case is not possible without making an exception to the first, which then leads to the selective application of fundamental rights and that is paradoxical.
Mass surveilance will undoubtedly unearth crimes that would not otherwise come under suspicion in a free society. By definition, the surveilance will also target those who have commmited no crimes. The question is whether that risk is worth it. The Fourth amendment says no. Making exceptions for certain classes of people (even if probable criminals) is just a slippery slope.
I don't think it is, and I hope most Americans agree.

You effectively contradict yourself: you can't say "no", reward them for doing it, and expect it to stop.
So effectively, your first sentence carries no weight, because you don't believe in enforcing it... you believe in rewarding law enforcement for doing the exact opposite.
