I am sure you all did this, but just in case - if you go to a protest; turn off your location services. Better to not bring your phone at all and use a cheap disposable or something...
At this point, the idiots at the capitol are mainly getting arrested because they had their location services on lmao.
Edit. I’m being told that my boomer tier understanding of phones is problematic. Read below plz.
turn the phone off and remove the battery and then wrap it in foil
not possible on all modern phones. wrapping in a napkin then foil so it doesn't conduct in the case of outer-shell-antennae models is good practice i suppose. but its a thing that can be done anything hot dogs are purchased.
