No. If we follow the letter or package analogy, lets say you are sending a box through a private firm (UPS Store). The UPS Store has to know:
- where the package came from, (shipping address)
- who paid for it (account information)
- where the package is going (delivery address)
- delivery restrictions
All of that information is not YOURS. That information belongs to the UPS Store. If they want to give up that information to LEO without a warrant, that is their choice - not yours.
I think my analogy is better. Yours if a physical object so UPS has a need to know if it could be hazardous. I suppose a virus could be in an email, so they have a right to make sure it doesn’t contain any, but you should still have a reasonable expectation of privacy about the content. New tech presents new problems, but the principle should be the same. And whether the ISP can give your content to a third party is yet another issue. But I thought what he wrote about was NSA metadata collection, which isn’t given by the ISP, just scooped up directly by the government.
Like I said though it’s not enough not to confirm. It’s one issue, and there will be other good justices to help him see the light on this, IMHO.
