Remember, when iPhones are off, they just become Airtags. Most modern phones are sending/receiving BLE signals even if you don’t expressly intend them to. I wouldn’t go anywhere near a protest with anything besides degoogled Android, because its the only OS where you can actually disable the radios. Even then I would probably opt for a Faraday bag.
Other considerations… Apple (and probably Google) devices are doing client side scanning of images and turning on GPS to geotag images unless you specifically disabled that features. In other words, there are ways you can be correlated to locations and activities after the fact. Just ask all those J6 rioters.
