    I find it fascinating how in the United States police radio communications aren’t encrypted and therefore anyone can listen to them. In my European country all emergency service communications are TETRA encrypted.

        EU security forces didn’t really care as TEA2 wasn’t backdoored. It’s a mid-90s standard with different encryption levels for different actors, it should be blindingly obvious that whatever is publicly available is backdoored. You may not like it, I do not like it, but it should’ve been obvious.

        The actual own goal was that while all EU security forces always had access to the secure stuff plenty of operators of critical infrastructure (think energy suppliers etc) used TEA1 as that’s what they were given. Also some EU forces bought TEA1 equipment presumably because they didn’t know what they were doing, with or without help from manufactures with an overstock of TEA1 radios.

        Here’s a 37c3 talk about the whole thing, from the people actually breaching the protocol.

        Aside from those encryption issues (which are finally getting addressed btw) TETRA is a great protocol, though. By now a bit dated so bandwidth isn’t exactly stellar (forget video streaming or such) but devices can talk directly to another just as in olden times, setting up a base station simply increases range, radio channels are now virtual, it’s all very sweet. Basically TETRA is to radio what GSM is to rotary phones. Which, as GSM phones don’t tend to be wired, makes a hell a lot more sense.

      Well, for starters, European police are actually trained professionals (in general, much more so than American police) and have different oversight. American police also handle a wider variety of things that really aren’t law enforcement - things that should be handled by other kinds of professionals.

      EDIT: American law enforcement agencies are also home to some of the highest rates of domestic violence perpetrators and right-wing extremism.

      American police shoot and kill 3-4 people each day. That doesn’t take into account deaths that occur in jails and prisons due to negligence.

      Not all llaw enforcement or emergency services are in the clear. The Feds are all encrypted (except for some intentional in-the-clear channels for open comms).

      One of the biggest criticisms after 9/11 was the lack of easy comms across agencies because of radio set ups, different 10-codes, etc.

      Hopefully this is something they are accounting for with this change.

      Also $400m doesn’t seem that crazy for an endeavor like this given the size of NYPD.

      40k officers and staff + backhaul + tower upgrades + vehicle radio upgrades and installation /$400m

      And is that $400m entire lifecycle cost? Over 5-10 years or whatever that’s really not insane.

      I think most eu countries use tetra for emergency services. it’s great for cross service group/task communications also.
