Yeah, the USPS cannot open your mail without a warrant, which is a pretty nice assurance to have. That would be pretty bad if it was how you described- all the more reason for us to make sure the USPS stays around :)

Edit: Note, this is a "nice assurance to have" because private shipping companies generally reserve the right to open anything that they are shipping.

Right. And that would be my point. That why do people use gmail and yahoomail, etc, when they have permanent records of every single word you write, but people would be outraged if the USPS scanned every piece of mail contents and sold it to advertisers.

And again, with private shipping companies, it's not like they are going to open 100% of everything. But the large email companies can, and have it forever. Can look at it 10 years from now, if they choose.
