If I want to have a private conversation where the details of what are said are undiscoverable, I believe that's a right that people should have in a "free country", including over the internet, over phone, and so on. The fact is, I can, using some combination of math and secrets, accomplish this.

I don't think anyone on earth has the right to collect/record/see the contents of my communications other than me and the other participants, until there's reasonable suspicion of a crime.

Covert dragnet snooping is an evil means to any end, and it damages the moral standing of the society that does it.
