We have no reasonable expectation of privacy anymore.
Emails and phone calls are vacuumed up and stored indefinitely for them to snoop through at their leisure and by their own admission they have already Hoovered up and stored so much data that they have no idea what to do with it.
They hide behind the National Security excuse despite the Fourth Amendment being quite explicit in that
The right of the people to be secure in their persons, houses, papers, and effects, against unreasonable searches and seizures, shall not be violated, and no Warrants shall issue, but upon probable cause, supported by Oath or affirmation, and particularly describing the place to be searched, and the persons or things to be seized.
So show me your probable cause that my personal Emails and phone calls are evidence in suspecting me of committing any crimes.
The onus should be on the government to do that for every single instance of them collecting and storing every, single, piece, of data that they collect.
They can't and they won't so they hide behind the blanket immunity of National Security.
I sometimes wonder if I speak the same version of English these people do.
