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.

    Stolen from another post:

    “you need around 6 layers of tin foil you can test this if you have a bluetooth device start playing some music or any audio and start wrapping in tinfoil until it disconnects id also say to leave your phone at home sk it pings the cell towers that you are at home and bring a burner if you can and make sure the burner is private so use cash prepaid sims and dont put the sim in at home or work make sure its all a mall away from cameras”

    You leave it at home. Take an old factory-reset with a prepaid sim. Keep it off unless you 100% need it.

    Your car’s GPS is also tracking your movements. If you have a newer car then your phone is only part of the problem.

      To be specific, it’s not the GPS receiver, it’s the fact that the car may be communicating via cell network or satellite, right?

        Right, but most modern cars have that communication built in, because they use it to update firmware remotely. You can’t turn it off even if you wanted to. Many car companies justify it by saying it is needed to give your location to emergency services if you use their alert button.

          Idk about other brands but with Mazda you can call and get them to deactivate your car’s sim. IIRC in Subarus you can just physically unplug the communication unit.

        Correct. Yeah, if you have a newer car with GPS, it will likely also have built in communications to the car company.

        There are benefits to older, “dumber” cars. Besides enjoying knobs and buttons 😁

    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.

      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.

    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.

    Burner phone … leave your main one at home … ABSOLUTELY DO NOT BRING YOUR MAIN PHONE

    Set up your burner phone with one or two accounts to things you might want to upload to … encrypt as much as you can. Do not load all your social accounts … only log into the bare minimum. If you are organized, log into temporary or fake or secondary accounts if you can.

    Start the day without any prior history, photos or content on the phone and keep as few contacts as you can … memorize numbers that are important to you.

    Always be prepared to give up or lose your phone.

    And as always … SAFETY GLASSES … bring a pair of industry rated CSA approved safety glasses (try to get a pair with a tint so you can pass them as sunglasses). Look for safety glasses with anything marked ANSI Z87+, sometimes written Z87.1+ (note the plus) rated or CSA Z94.3 rated are ensured to safely withstand a direct high energy strike.

    … additional things if you want to do more

    Bring a small new blank paper note book you can keep in a pocket with a small pen or pencil … you might be taking notes like license plates, name tags or names of people or places … its always faster to just write something down than in taking a shaky photo or tapping away a note on an app

    Wear a big scarf … for guys or girls … a scarf comes in handy for all kinds of emergencies including using it as something to cover your mouth, dress a wound, tie something or cover something up.

    Wear a good pair of running shoes … be prepared to run and be on your feet all day.

    Bring a small backpack and bring a couple bottles of water and some energy bars … keep it light because you’ll be on your feet all day and if things go bad, you might be targeted if you have a large pack … plus an empty pack can be used to carry things later if you need to.

    Dress for the weather … if its going to be hot, wear light clothing but if things go bad and you have to stay out over night or longer, bring a light jacket … if rain is forecast within a day or two, bring a small poncho

      Everyone should look up what a shemagh is, and all multitude of uses it has. Pretty sure there are plenty of colors that aren’t tacticool, which is inevitable when you search for it. If it works for the grunts the US sent to the Middle East, and actual Middle Eastern cultures, it’ll work for you. Hitchhikers’ Guide to the Galaxy describes how useful it is to carry a towel across the galaxy; this is it.

      Edit: something more that I recalled of when I was in the prepper phase years ago: Marines swear on this thing called a woobie. It’s their safety blanket, figuratively and practically. It’s basically a quilted fabric liner under a poncho for insulation. Works just as well as blankets if you’re going to be crashing somewhere overnight.

      To add onto the phone section: (1) Disable any biometric authentication, and (2) turn/keep it off whenever there’s a chance that it will be siezed.

      1. While the first amendment protects you from being required to give up your phone’s pass code, there’s no protection against someone just holding the phone up to your face or fingerprints to unlock it.

      2. While your phone is never totally impenetrable, it is significantly harder to access in its BFU state (before first unlock). Most commercially available cracking tools will only work if the phone is in it’s AFU state (after first unlock).

          And in all likelihood forcing your fingerprint or face unlock is perfectly legally acceptable for them to do. A password or a code is something they’d have to force you to say and ultimately you can choose not to (though they’re still fine to just try and hack out a pin/pattern on their own, or use phone-cracking tools or backdoors) but you have no defense whatsoever against your biometrics being used.

      Ideally, that burner phone never goes anywhere near your home or any place you frequent from the time it is acquired until the time it is destroyed.

      Briar is a good messaging app for you and your group. It will work (to some degree or another) over bluetooth even after they shut down the cell towers. Keep posting information about law enforcement deployment numbers and locations.

      Airplanes.live provides unfiltered ADS-B data, useful for identifying and locating law enforcement aircraft, including drones.

      For uploading media, choose overseas fediverse instances for your account, which are not subject to US law, and won’t get shut down or raided by US law enforcement if you upload something they don’t like.

      I’ve been suggesting this everywhere: pick a dozen different protest locations, and share your list with everyone you meet. If and when law enforcement deploys in force at your current location, leave for another. Force them to constantly redeploy to multiple locations.

        Do not use Smartphones. For the scarf use an unmarked tubescarf, its easely hidden in any collar. Cary bandages and lightsalt solution, like you use for contacts, to treat teargas and light wounds. If they get you you want nothing outside oft your memory that has any link to others. Depending in the effect of carrying your passport with you in your country decide wether to take it along.

          Smartphones are far too valuable to our efforts to be left at home. They are the difference between personally observing law enforcement atrocities, and being able to prove them. The media isn’t covering the protests. We need as much video as we can get. We need to be able to coordinate efforts, passing along troop deployments and numbers.

          While our main phones and accounts are probably linked to more information than law enforcement should ever be allowed to touch, burners add too much to our efforts to seriously consider not bringing them.

      We’re so focused on electronics here, but this part can save your ass:

      Bring a small new blank paper note book you can keep in a pocket with a small pen or pencil

      The following is translated from the meager tactical training I’ve received: Emphasis on the pencil being small. You definitely don’t want a full size pencil in your pocket if shit hits the fan and you get tumbled.

      Maybe get a waterproof notepad. But make sure that you can easily rip out pages. Use a single sheet for all the info you don’t want the police to have (like all the other burner phone numbers and such) That way you can rip that sheet out and swallow it, if you’re about to be captured.

      Also, about the scarfs. I don’t know about the US, but at least in my own country, it’s illegal to use a mask at protests. Meaning a mask would get you singled out and targeted by law enforcement.

          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.
