The NYPD is spending $390 million on a new radio system that will encrypt officers’ communications — reversing a near-century-old practice of allowing the public and the press to listen to police dispatches.

But I thought you said E2E encryption a danger to national security, hmm?

You said you wanted a backdoor, didn’t you?

If you have nothing to hide, you have nothing to fear, right? Right?

Standard double standard bullshit.

[–] ares35@kbin.social 56 points 10 months ago (3 children)

tbf, cops 'doxx' people over the radio all the time. not just suspects, either, but potential witnesses, and normal folks caught-up in 'stop and frisk' or 'papers, please' stops. full legal names, birth dates, genders, government id numbers, addresses, and so forth are broadcast for all to hear. that data should be encrypted, and is in many jurisdictions already.

[–] pennomi@lemmy.world 6 points 10 months ago (1 children)

Not just that data should be encrypted, ALL data should be encrypted, with very few exceptions. It’s scary how much privacy we lose through unencrypted communication.

[–] agitatedpotato@lemmy.world 11 points 10 months ago (2 children)

Its illegal for citizens to encrypt their own radio transmissions, so no one else can legally do this.

[–] Dubiousx99@lemmy.world 3 points 10 months ago (1 children)

How so? Your WiFi broadcast is encrypted. Your cellphone signal is also encrypted. The FCC doesn’t bar encryption. https://www.govinfo.gov/content/pkg/CFR-2014-title47-vol5/pdf/CFR-2014-title47-vol5-sec90-553.pdf
Now this last point is only relevant for the US but generally laws governing radio transmissions are fairly similar around the world.

[–] GrayBoltWolf@lemmy.world 5 points 10 months ago (2 children)

In HAM radio, encryption is forbidden, which would be the most equivalent to police radio.

[–] Dubiousx99@lemmy.world 5 points 10 months ago* (last edited 10 months ago)

HAM radio is amateur radio, rules and frequencies are established with the goal of promoting amateur use. Emergency service use would be a professional use and are licensed separately. The statement that citizens are not allowed to encrypt traffic should instead say that HAM radio operators are not allowed to encrypt their communications in accordance with their license.

[–] SkybreakerEngineer@lemmy.world 4 points 10 months ago

Yeah, that's not how FCC or ITU licensing works

[–] skuzz@discuss.tchncs.de 1 points 10 months ago* (last edited 10 months ago)

I swear there used to be a law on the books that specifically said this, and it included police radio as they use the RF spectrum owned by the People. Police radio would be unencrypted and it would just contain the day-to-day traffic, and anything sensitive they'd transmit via other means like Nextel or even before that, the police phone booths.

IIRC it was one of those "check and balance" things to keep police honest. Although I haven't been able to find any law stating this, so perhaps I am mis-remembering some other law.

As for encryption in practice, cellular is encrypted, as others mentioned WiFi is encrypted, satellite communications are encrypted, a whole bunch of radio traffic is encrypted.

To counter @pennomi@lemmy.world , no, all transmissions should not be encrypted. The lack of openness and transparency by creating closed systems means there's no more "watching the watchers" and we have to take organizations in power at their word. Most human communication dating back centuries was not encrypted, and humanity got along just fine.

Likewise, when we assume our communications are "secure" we all are much more willing to share things over networks that we probably shouldn't. It makes security on the human side inherently lazy. Think about all the things people probably share over iMessage that they shouldn't. Apple has the keys to every conversation. A bad actor could gain access to a whole bunch of peoples' personal data they just assume is safe.

There are places where encryption should be used, but it should be used thoughtfully, not just, "lock it all down." It creates a dangerous complacency factor.

It is a very gray area topic that does not have one universal answer.

Edit: Formatting.

[–] dangblingus@lemmy.world 3 points 10 months ago (1 children)

Don't you see a problem with that? Surely the answer is to communicate sensitive information via a different method, and not over the air where civilians are supposed to have transparency with emergency services. Transparency meaning checks and balances ensuring less corruption. Protect people's identities by using the new encrypted channel. I don't care if the officer has to press a different button to make the call.

[–] ares35@kbin.social 6 points 10 months ago (1 children)

they do often use other devices (laptops in cruisers, for instance) but away from their vehicles, the radio is usually what gets used.

[–] constantokra@lemmy.one 2 points 10 months ago (2 children)

Sorry, that's laziness. Also, for literally no cost they could use a phone they already have, or even have an app on the phone that both encrypts any data they want to send and encodes it in soundwaves that can go out the radio. Whoever's listening at the police station could have an app running to automatically decode and display the sensitive data. This stuff isn't hard. It's only hard when you don't care about people and you don't get consequences for it.

[–] kebabslob@lemmy.blahaj.zone 6 points 10 months ago

Cops are lazy bro

[–] nova_ad_vitum@lemmy.ca 0 points 10 months ago (1 children)

This stuff isn't hard.

You want to know how I know you've never built anything of this scale before?

[–] constantokra@lemmy.one 2 points 10 months ago (1 children)

Amateur radio operators, like myself, do this stuff all the time. There are already open source apps that do exactly what I mentioned, with the exception of encrypting the data, because that's not allowed in the amateur radio service.

How exactly is any of what I said too hard for a 350 million dollar budget? Or do I have to personally design and implement a perfect solution for an.entire municipality to be able to even comment on a subject I know a good deal about? But yeah, go ahead thinking it's level of difficulty standing in the way of a reasonable solution instead of a desire for even less accountability.

[–] nova_ad_vitum@lemmy.ca 2 points 10 months ago

No they don't. Unless you want to tell me how amateur radio operations routinely operate a large scale critical system with inventory management, tech support , redundancy, and a myriad of other shit that hobbyists don't have to care about.

There are already open source apps that do exactly what I mentioned,

Which doesn't come close to implementing the same capabilities as the system in question, nor does it operate within the same constraints. All you saw was the word "radio" and assumed your hobby makes you an expert.

How exactly is any of what I said too hard for a 350 million dollar budget?

It's not, they're doing aren't they?

Or do I have to personally design and implement a perfect solution for an.entire municipality to be able to even comment on a subject I know a good deal about?

You can comment on anything you want with any level of knowledge you want and I can comment on that comment which is whats happening. Thinking you know how to do this because you mess with amateur radio is like thinking you can implement a web portal for national healthcare services just because you learned some JavaScript and Python.

[–] ExfilBravo@lemmy.world 31 points 10 months ago

They wont use that to abuse their position. no way. /s

[–] TomMasz@kbin.social 4 points 10 months ago (1 children)

I assume this means encrypted P25 . Public service agencies have been using it for years, though not all of them encrypt.

[–] enki@lemm.ee 3 points 10 months ago (1 children)

And it's easily decoded when you have the keys which, based on every other department that uses them, won't take long to leak or be cracked.Lot of folks use SDR setups on a PC to decrypt and stream police and fire radio to a service like Broadcastify

[–] MimicJar@lemmy.world 2 points 10 months ago

From a legal standpoint does that change things? Especially if the keys aren't intended to be public?

[–] irmoz@reddthat.com 3 points 10 months ago

Right, so now they're operating in total secrecy. Nothing at all like a gang!

[–] Altomes@lemm.ee 2 points 10 months ago

Yeah fuck that
