Don't forget the 3D geo-mapping tech that can accurately monitor you everywhere you go. And the science fiction-grade remote field microphones that can listen to everything you say. And I'm sure I don't need to mention they can watch everything you do on your screen in real-time, regardless of VPN or any counter-measures you attempt to take.
They know everything about each and every one of us. No secrets. We're test subjects. Whether it's "legal" or not is of no consequence; this is a matter of national security and virtuallyanythingcan be justified when under that umbrella.
