Before going to a protest, demonstrators or observers should note that their cellphones may subject them to surveillance tactics by law enforcement. If your cellphone is on and unsecured, your location can be tracked and your unencrypted communications, such as SMS, may be intercepted. Additionally, police may retrieve your messages and the content of your phone if they take custody of your phone, or later by warrant or subpoena.

    people on the internet love to talk about all these great security smart things that they will definitely never do.

    leave valuables at home, wear unremarkable clothes, and write your lawyers number on your arm with a sharpie.

    personally i bring my phone and a leica. ive been to jail for protesting before and in my current situation i just don’t care.

      Its important because you endanger not just yourself but anyone who is possibly linked through your activities. Your actions are your own responsibility. If you are able to protect others in this Situations you should. And i hope you only document voilation oft power with your leika and not others protesting.

        i don’t know what you just said but the whole point of a protest is to disrupt in order to be seen.

        I went to jail for trespassing. same as everyone else. its bullshit.

    Leave it at home.

    I can understand the wish to film things; I recommend buying a cheap camera, maybe one to strap on your forehead (starting at $20) or an old compact digital camera. Something without any sort of connectivity. Something you can leave behind if the going gets rough.

      Also multiple SD cards, swapping out frequently so even if they grash the camera you still have something.

      maybe one to strap on your forehead

      They make much more practical chest straps for things like GoPros - you can sort of forget it’s there and just let it capture everything. I did that while white-water rafting and it worked very well.

          Faraday bags work, period, if they are made and used properly. If there’s no RF getting in or out, there’s no GPS and no checking in with the towers. Inertial navigation doesn’t work worth a damn after a little while, and it won’t work at all when powered down. Obviously? black tape over the camera lenses unless you’re ready to share what they’re seeing, and the microphones can listen very well too, it is a phone after all, so bear that in mind.

    I learned this recently: if you have an iPhone, pressing the lock button five times rapidly will lock it so that you need to enter a passcode, not just FaceID. Useful if you think somebody might forcibly use your face to unlock it

      Yes, but this will also call emergency services after, I think, ten seconds.

      Make sure you cancel that call right away unless you actually need them.

        Honestly, it would be kind of funny that your phone calls emergency services when you get pulled over and you don’t want them to force you to unlock your phone, having a 911 operator recording the entire interaction’s audio.

    Buy a feature phone in cash at a Dollar General as far away from home as you can feasibly get. Do not interact with any other business in the area. Just buy the phone and leave. Activate it at a public library. Add no contacts. Tell no one that it exists.

    If your phone is powered your location can be tracked. Secured or not: your location can always be tracked.

    The rest is doubtful, always assume law enforcement has access at will.

    Just don’t bring it.

          so you’re going yo trust the government funded org to tell you how to not be tracked by the government?

          better yet, you’re going to trust the company that actively works with the government under national defense that wants to track you to protect national defense?

          no thanks. I’d rather be safe than detained.

            Until I see a shred of evidence that airplane mode doesn’t disable the radios, yes, I’m going to trust the manufacturers, the EFF, and my background in EE

              I tend to agree (and also an EE). Airplane mode isn’t a total panacea, though. It just disables the cellular radio. While it also disables the Wifi and Bluetooth, those can always be turned back on, even while Airplane Mode is active. A motivated state actor can absolutely track via Wifi or Bluetooth. (Possibly even NFC, but the range on that is so low that I think it would impossible to do without seeing what is tracking you).

              Turning the phone off is the best solution if you want to keep rhe phone on your person. Guaranteed that all possible avenues for tracking is off, and also has the advantage that even if the phone is seized, the latest phone OSes require the passcode before doing anything at all when they first power up. Even the Police are limited in the data they can get off a phone that has just powered up and is asking for the passcode.

    You get a burner for the protest and give your phone to a friend or family member for the day so that it still pings towers at the usual places.

      Pointless, unless you leave the roomba running outdoors. Indoors you don’t have GPS coverage, and your phone is logged onto the same cell tower anyway. Might just leave it stationary at home, same outcome.

          Why do you need an ID? Leave it in your car if you’re driving.

          I don’t think there’s a single state that requires you to actually carry documentation.

          https://en.wikipedia.org/wiki/Stop_and_identify_statutes

          These are the states that require you to at least verbally state your name, and only if the officer has reasonable suspicion that you have or will commit a crime.

          They can ask your name. You may not have to answer.

          Research your state’s law on this before you go. It’s in the link.

            There’s legal requirements, then there’s practical dealings with officers in the field. Seems to me that these days if you’re “undocumented” you’re asking to be sent to processing which can be a quick trip to a center somewhere across the country, if that’s the mood they’re in. After you get out you can try to sue them, maybe even win, but how long before you collect your damages?

              This. You’ve got to ask yourself, what your goal when interacting with law enforcement is. It it your goal to stand up for every right? Or do you want to get away for the interaction as easy as possible?

              Let me give you an example of what I mean. I Denmark police can stop and ID you without a cause. You don’t have to provide an ID, but you have to state your name, address, and birthday. If you don’t, then you’ll be arrested. Our SSNs consists of birthday and a checksum. You’re not required to state your SSN checksum, but if you do state it, the police will have to pay you if the stop is longer than 10min.

              So giving the police a little more than they’re entitled to, can get you out of the interaction a lot easier.

              Of course you can stand up for your rights, and if you want to fight, then do it. But it will make your day harder.

                When they’ve got a cell full of detainees and they’re deciding who ICE is going to ship to “advanced processing” who do you think goes to the front of that line? I’m guessing it’s the “undocumented,” regardless of whatever laws you’re focused on.

      What’s wrong with a grapheneOS device on airplane mode? Is firmware level tracking a confirmed thing?
