As the Internet we need to do two things, one start getting our sorry little asses in congress to stop this stuff where it starts.
Two, build better technology that is not such an easy target. If individual keys were required to decrypt messages, then it's hard to take the data without your permission because cryptography prevents that.
This might be a good enough reason to switch off of email, especially email like gmail.
As EFF reports, large email providers (one assumes this includes GMail) have a practice of demanding warrants for email, even though the FBI is in some circumstances technically entitled to email with just a subpoena. The FBI apparently (as far as we know) hasn't litigated any of these cases, and has simply obtained warrants.
It doesn't seem unlikely that we're converging in the short term on a legal terrain where all access by law enforcement to email is going to require a warrant.
