Snowden warned us years ago. This whole FISA court thing is a sham. The feds stopped using the process years ago.
Why? They can just mine everything off the internet. Whatever you signed up for, Google, Facebook, Instagram, virtually any app, etc., all required you to waive your rights in all of your data, not just what was needed for the app but everything else as well. So the federal government takes the position you have no privacy right in anything of yours that is out there on the net. They just grab it, either directly or through mining it through back doors in the tech companies.
How do you think they tracked down all the “insurrectionists”? They started with your travel records, credit card information, and then moved on from there to whatever you or anyone else might have posted on Facebook. They can pick your face out of a crowd with facial recognition technology and databases created by Facebook.
I should have added they know where you were at any time because your cellphone monitors and keeps track of all your movements.
