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.

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

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).

I've seen plenty of videos of cops holding a suspect down and forcing a fingerprint unlock...

[–] rob_t_firefly@lemmy.world 6 points 2 days ago

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.
