Extracting video and audio from used police body cam
- icholy 6y agoI just see two pictures of a disassembled camera. Is there more info?
- Kaze404 6y agoThere's an entire thread under the linked tweet.
- emilfihlman 6y agoTwitter UX sucks pretty badly, especially for those who have not used it much.
- Kaze404 6y agoI don't like Twitter's UX either, but to get to the rest of the thread you just scroll down? Isn't that how we've always viewed documents on the internet?
- emilfihlman 6y agoNope, that's not how it's visible to me. I just see 2 posts with images, and then "comments" to those have new images but clicking on them does not allow me to conveniently view the next one but have to instead return back and do the whole process from the start.
- ikornaselur 6y agoYou have to open the link OP posted here and then click the top tweet for it to open, then you can scroll down. Without clicking it, you only see two tweets with no indication there's more. I only see 4 photos at that point and have to click "11 more replies" to see more, but there's no indication that there's more before you "open" the first tweet.
- Kaze404 6y agoWeird. Maybe it's because I'm logged in, but clicking the link immediately lets me scroll through the entire thread.
- strathmeyer 6y agoForth tweet says "so this happened" and is a picture of a wedding ring on a woman's finger. Next is a Voltron gif, a pic of some woman's makeup, and a fantasy corset.
- rkangel 6y agoI agree. But that's partly because people are use a microblogging platform to post things that are definitely not micro blogs.
- emilfihlman 6y agoExcept a microblogging platform would probably work here, even though Twitter doesn't.
- MaxBarraclough 6y agoWhich may or may not show. I had to refresh to see that thread. (I loaded the URL again in a fresh Private Browsing window, and sure enough, I didn't see the thread.) Another reason Twitter is a poor substitute for a blog post.
- Jaruzel 6y agoIt's all unrolled here: https://threadreaderapp.com/thread/1278413772680507392.html https://threadreaderapp.com/thread/1278413772680507392.html Personally, I think this is bad form. He should have quietly told the seller that the data is recoverable rather than broadcast it all over Twitter. The last thing we need is the Police finding reasons NOT to wear bodycams.
- grawprog 6y agoAll police body cam footage should be public. Their work is paid for by tax money, they are supposed to be public servants. Governments, including their police force should be transparent to public they're supposed to be serving.
- Jaruzel 6y agoAnd if you were falsely arrested, and had the footage out there without your consent, you'd be happy for that too? It's a double edged sword I think.
- gruez 6y agoI don't think the parent comment (or anyone for that matter) is advocating for the unauthorized public release of bodycam footage. I think his point is that as public servants with extraordinary power, the public interest trumps any personal expectations of privacy while on the job. As such, the public shouldn't tolerate "but privacy!" as an excuse from police officers not to have bodycams.
- tmoravec 6y agoWhile I agree with the sentiment that public workers should be accountable to the tax payers, let's not forget they are still humans. Would you like your employer to point a cam at your desk and have it recording at all times?
- grawprog 6y agoFortunately, my job doesn't require me to carry firearms, detain citizens or uphold laws. Furthermore, when I was being paid by government grant money, we were accountable for every thing we did while being paid and every penny we spent. We were required to make regular reports and justify everything. It'd be nice to see even that level of accountability with policing.
- MasterScrat 6y agoYou need to follow the twitter thread. Click the first tweet (or go to https://mobile.twitter.com/d0tslash/status/1278413772680507392 https://mobile.twitter.com/d0tslash/status/12784137726805073...). Then scroll down and click on "more replies" to keep going. Feel free to curse Twitter's UI/UX along the way.
- pininja 6y agoA little further down the thread they post the success! https://twitter.com/d0tslash/status/1278458524742361089?s=21 https://twitter.com/d0tslash/status/1278458524742361089?s=21
- TheChaplain 6y agoUh, I'm not sure it's a good idea to post pictures of the camera footage on Twitter? Especially as one also have military personnel in it...
- deleted 6y ago[deleted]
- LockAndLol 6y agoI this guy opening himself up to a lawsuit by publishing everything like that? Last I remember, people got nailed for simply pointing out there was an issue on a server and with anti-repair laws out there, you never know what's gonna happen.
- loeg 6y agoThis isn't a remote server; the cameras were acquired legally by the tweeter.
- bathtub365 6y agoGiven that police are fine with torturing and killing people illegally, I don't know that this will mean anything.
- LockAndLol 6y ago> Please respond to the strongest plausible interpretation of what someone says, not a weaker one that's easier to criticize. Assume good faith. https://news.ycombinator.com/newsguidelines.html https://news.ycombinator.com/newsguidelines.html Please, read the guidelines. It should be pretty clear that I know an SD-card isn't a server.
- colejohnson66 6y agoWas it legally obtained? Purchasing an illegally obtained good is still illegal in the US.
- damagednoob 6y agoThere's a few comments about the legal status of doing this. In the US, wouldn't this be considered dumpster diving(https://en.m.wikipedia.org/wiki/Dumpster_diving https://en.m.wikipedia.org/wiki/Dumpster_diving) and lawful?
- deleted 6y ago[deleted]
- jcrawfordor 6y agoThere's plenty of precedent to find dumpster diving (or more specifically using sensitive information obtained that way) unlawful in a variety of situations. Most precedent in support of dumpster diving for sensitive information is in the context of law enforcement searches which are regarded somewhat differently by courts than a random individual obtaining sensitive information with questionable intent. Just Wikipedia mentions a case in which the dumpster-diver was ordered to pay damages in response to sensitive information retrieved by dumpster diving. It's just doesn't seem at all clear-cut that what the person here did is legal.
- bob1029 6y agoI believe if the device is obtained lawfully, there isn't much anyone can do regarding what you then decide to do with it or any of its contents. This is precisely why you should drill through hard drives and flash media before removing them from your secure areas.
- GhostVII 6y agoSeems crazy to me that they don't encrypt the videos on the device given how much personal information about other people can be on there. There is a full video of the inside of someone's house in that feed. Couldn't they just have some kind of public/private key encryption, where they put the public key on the bodycam and have it encrypt all the videos it takes? Then you could just decrypt them at the station with the private key.
- bob1029 6y agoPKI is insufficient protection in this case. If someone obtains the hardware and has a few years to sit on it, it is possible that private keys can eventually be broken (or compromised via other channels).
- Wowfunhappy 6y agoMaybe so, but not using encryption at all is clearly worse. What would be a better system?
- bob1029 6y agoHardware security. These devices should have been built from day 1 with the idea that they would eventually need to be retired from service. They could be designed to self-destruct their own memories if a certain signal is not received within a certain timeframe. Procedures would be built around this such that cameras would need to be periodically checked-in for audit and refresh of the hardware kill timer. If an officer fails to check in a certain camera (presumably with the intent to expire the hardware timer), you could assume malicious intent and have whatever arbitrary penalties to discourage this behavior. Set the timer at 48~72 hours and it would be virtually impossible for even the most sophisticated attacker to physically breach the HSM in time for extraction of the data/symmetric key. Combine this with a PKI and you should then have a solid solution. If you want maximum traceability, you could throw in LTE or satellite connectivity for logging major audit events or triggering certain device features remotely.

- floatingatoll 6y agoEthically, it’s inappropriate to post some of these photos without blurring identifying details that are not material to the newsworthiness at hand. We don’t need to see the officers’ unblurred faces to confirm that these were successfully extracted from a random eBay purchase, as their precise identities are not relevant to the story. We do need to see the cop cruiser unblurred, because that’s materially relevant to the story and serves as likely (but not certain) evidence of the source of the images. We don’t need to see the exterior shot of someone random person’s house, because that could result in their location being identified and the press mobbing them pointlessly. We do need to see the safe interior shot of someone’s house, that doesn’t reveal any identifying information, since that protects their identity while supporting the story at hand.
- dependenttypes 6y agoI disagree, ethically it is not only fully appropriate but also mandatory to post everything that said cameras contain.
- GTP 6y agoWhat would have we lost if he burred the faces?
- VWWHFSfQ 6y agoBody camera footage has to be reviewed and made public if appropriate. But not all body camera footage should be made public. To protect the rights and privacy of the innocent.
- xfitm3 6y agoIt's this exact mechanism that allows police to bury mistakes. Rarely are the innocent truly protected.
- jayrice257 6y agoThen how do you know if it's rare?
- x87678r 6y agoFrom the link it isn't clear. The guy bought a cam from ebay and found the pictures still on there, which is what he's posting on twitter. https://www.azmirror.com/blog/fort-huachuca-police-body-cam-footage-easily-accessible-after-an-ebay-purchase/ https://www.azmirror.com/blog/fort-huachuca-police-body-cam-... Its kinda sad, I love the idea of reusing old electronics instead of dumping them, but is usually too difficult to secure.
- david422 6y agoYea, this is why companies destroy perfectly good hardware- so this doesn't happen :(
- mothsonasloth 6y agoA more appropriate medium would have been a technical blog post, with redacted information and blurred photos. Not an attention seeking twitter thread with lolspeak...
- WarOnPrivacy 6y agoCompletely made my day. I can just gush with love for stuff like this.
- coronadisaster 6y agoI'd be scared for my life if I was him... hopefully he posted that stuff anonymously. I've seen some white people getting killed on video in a similar manner to George Floyd's killing, but even worst (i.e.: The police have the medic inject the victim with strong drugs right after he passes out from getting choked to death). This video is very troubling but if someone wants to see it I will post it (what is even more troubling is that no one lost their job).
- lsh 6y agowhat a doofus. > Me trying to extract video from this body cam like: OHHHH please work! more like: "me putting my head in a lion's mouth"
