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.
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.
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.
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.
It seems insane that they were communicating out in the open.
On the one hand, you probably hear all kinds of cool shit. On the other hand, how in the fuck are they just discussing all their sensitive shit out in the open??
To keep the private info of the people involved actually private. License plates, descriptions, home addresses, personally identifiable info. It seems mad that all of that is just broadcasted out to everyone. Probably wouldn’t even be legal where I live because of privacy concerns.
License plates are not private, they literally sit out in public all day. Descriptions are, again, not private. Even your license info is public.
Not to mention, police reports are info that can be requested with a FOIA request. So all that info is public anyway, even if it was originally private.
I mean… Let’s just take your example of “we have a jumper at x and y street”. Is it really a good idea to have everyone know that? Do we want “journalists” to drive over their and take pictures of people in crisis (possibly worsening it).
Or let’s imagine a car chase, do we really want criminals to know that a spikestrip is set up 2 streets ahead?
Do we want information like warrant and licence checks to be held over unencrypted radio transmitions. Allowing everyone who wants to to listen in and learn about people’s criminal histories?
Just to add, I am aware that the whole idea of privacy isn’t really a thing in the US, the names and mugshots of arrested people are literally made public in some (all?) states, so you probably don’t care about the last point, but the rest still stand, and in lots of countries everyone’s privacy is considered a right, including that of (suspected) criminals.
Is it really a good idea to have everyone know that?
It really doesn’t hurt.

How is a journalist any different than a dozen randos posting it to TikTok? At least the journalist would be more likely to report facts instead of “#justdoit”.

his isn’t usually a concern. Spike strips are set up pretty much only when the criminal has no other option. They aren’t done in a residential area where there are many side streets and turns, because it’s like trying to herd cats.
Most of the time in a chase, it’s info the criminal is already going to know. Where they are, what they are doing, etc. the cops don’t normally detail their plans on the radio, just communicate info.

This info is already public. You can literally just look it up on government sites. You can do that in many different countries, in fact. And I’d say that’s a good thing, actually. Why should we keep criminal activity private? How do we keep both citizens and government accountable if we aren’t open about what was done and the punishment received. Otherwise you can have people just disappear from the street into a jail cell, and the public have no way of ever knowing.
Communicate private health information? A lot of times they still use fax machines. Information can also be stored in a secured database where access is recorded and monitored. If needed, they can always pick up the phone and talk directly with a person if you need something. HIPAA is fairly specific about this.
An encrypted two-way radio, where only the two parties requiring the information would be on the call, that might be fine as long as you’re careful to make sure someone standing nearby can’t overhear. But that’s not what NYC is building.

Which had/has a built-in backdoor for years.

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

Wait the CCC speaks English? I thought they were German!
Projecting a wee bit, aren’t we?
Also the presenters are Dutch. The congress is bilingual though IIRC simultaneous translation is only in place for German->English.
CCC was founded in Germany. It’s not strange to assume they’d publish in German.
Oh they do. And if it was a rabbit breeder association it would stand to reason that they’d only publish in German, but they aren’t, and they don’t.
Du hast mich gefragt!

What do American police handle that European police do not?
He already stated that. They shoot and kill 3-4 people a day!

They don’t? I mean, you can listen to them, they are not discussing sensitive shit because it’s public.
So what do they use to do that? Or is it that they can’t because they don’t have a secure channel?
Cell phones are a common option.
Jesus. I can’t believe they haven’t encrypted sooner. “We have a situation here, wait let me call you.”
Why would the situation need to be kept private? “We have a jumper at this and this street”, “shots fired on scene”, “I ate a burrito.”
I’m honestly curious, what vitally secret info do you think needs to be communicated over radio? They aren’t for conversations.

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