Holy shit I actually did tell my daughter not to bring her phone to the protest.

May I know what's the reason to not bring your phone? Is it due to concerns of being tracked?

Yes. Even when your phone is powered down, some models still ping cell towers. If it pings one, they know your distance to the tower. If it pings two, both towers know your distance, and the overlapping circles would reveal two positions coordinates, one of which you were at. With some contextual information, it's easy to know/prove which one you were at.

If it pings 3 towers, your exact location, and unique identifying information sucha as your phone's IMEI is revealed. So don't bring a cell.
