Shared here for public benefit.

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.

Leave it on at home.

Not that that'll actually work or that they'll care, but still...

Even better, have your tv on the whole time, so if the tv sends telemetry data that's also linked to the phone, it'll show you were at home the whole time.

They likely have the data to show it didn't move at all. Eg it wasn't on your person.

Ask a non-protesting friend or family member to take it with them about their daily routine?

I'm sure my mum would be happy to look after my phone for a day if it meant getting one over on three authorities. And if anyone asks, I'm just a good son who likes to hang out with his mum.

You underestimate how much of a couch potato I am. Not moving is normal lol.

[–] KingPorkChop@lemmy.ca 2 points 5 hours ago

If I'm sitting on the couch, the phone is not on me. It's on the table next to me or on a counter somewhere. I don't even always look at it if I get a message. Sometimes I'll wait hours after I get a message to read it.

Even sitting on a couch moves your phone more than simply laying on a table. They can use accelerometer data to determine how, if at all, it moved.

For that , someone mentioned a roomba or straping it to a dogs collar..

Put a harness on your pet and put it on the harness. Boom, instant spoofing.

Movement data shows that you scratch your fleas a lot, you should do something about that.
