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"

Be safe tomorrow everyone

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.

I did say that. But yes. Use cash whenever possible.

Sometimes my eyes go faster than my brain. Skipped that word completely.

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.

Some very cheap phones with minutes included, here:

OTOH they can probably be traced back to you since you have to order them with your presumably real name. You can buy phones and prepaid cards anonymously in phone stores but it will cost more.

Well, they are called TracFone 🙃

The powers that you are necessarily taking these precautions against are all funded by your taxes.

[–] athairmor@lemmy.world 3 points 1 day ago

Yes, that’s why they are protesting.

Don't bring it
