      After 9/11 there was a government move to centralize communication among first responders. Lots of money allocated for new digital encrypted radio.

        I thought this went further back to like ~98 and lawsuits around “export grade” encryption and the NSA was partnering with cell phone providers.

          Rumor Control: there are 5 levels of encryption on a digital GSM over air call. It’s pretty much bullet proof. But, you can trick the phone or like the NSA get the call straight from the switch.

            That’s because they’ve relaxed on it a bunch. Also, the stuff they were pushing in the 90s really wasn’t secure.

            There was a Darknet Diaries episode that covered a lot of this, but I can’t remember which one.
