There is something to be said for bringing your phone to protests so you can livestream them to the world when the authorities use heavy-handed, violent tactics to stop them.
While I agree that filming is important, it’s also important to remember that between the J6ers being dumb fucksticks and their social media site being absolute dogshit, a lot of them were caught because EXIF data wasn’t scrubbed. Having one’s phone with you could end up being the thing that gets you prosecuted.
In all honesty, it would probably be best to have a dedicated device for that situation as well so that if they choose to search it then all they will get is the footage from the event.
