I think there's an idea akin to Europe's "right to be forgotten" here. We can all observe the world in the moment. Police can obtain warrants to wiretap (or the digitial equivalent) suspects in real-time. That's fine! The objection is that we are ending up with laws and rulings that require a recording of history of everyone by everyone - just so the police can have the convenience of trawling through data everyone reasonably felt was private and shouldn't exist except transiently? Not to mention that perhaps the state should pay for all this commercially unnecessary storage? Our digital laws are so out-of-touch with the police powers voters actually consented to - that mail (physical post) and phone calls shall not be in intercepted except under probable cause (of a particular suspect performing a specific crime) and a judge's consent. Just carry that concept forward. On a technical level, I feel a "perfect forward secrecy" technique should be sufficient for implementers. A warrant should have a causal (and pinpoint) effect on what is collected by providers. Of course we can also subpoena information that everyone reasonably expected was recorded (i.e. not transient and private). This matches the "physical reality" of yesteryear - the police can't execute a warrant for an unrecoreded person-to-person conversation that happened two weeks ago; you need to kindly ask one of the conversents (who have their own rights to privacy / silence, are forgetful, and can always "plead the 5th").
