With reports that the witnesses in today’s murder by ICE were all detained (and their phones presumably confiscated), I’ve been thinking nonstop about if I were to record ICE or the cops doing something, how could I ensure that any videos I record are not able to be deleted, assuming my phone was confiscated? I’m talking about specific tactics.
My phone runs iOS. I already have a strong passcode which hopefully makes brute forcing difficult. I use ADP and the only thing I back up automatically are photos and videos. In theory, I think my setup is fairly secure, since it would be hard to get into my phone or my iCloud account. But I don’t know what vulnerabilities or tools I may be missing.
I’m asking for iOS, but I think it’s good to discuss Android and GrapheneOS as well.


I’m not so sure this is the case, at least not trivially. There’s a reason the feds sued Apple trying to get them to unlock that one guy’s phone. Same goes for Android, the most important part is not using biometrics (face, fingerprint) and set a 6 digit pin (or whatever max it allows for).
Before going somewhere hot like a protest, make sure the screen locks automatically when you click power off button, and screen timeout to minimum. Make sure beforehand that your phone has device encryption turned on.
If you use something like google drive or whatever, make it auto-upload your photos/videos, and rather take many shorter videos than one long one, if you find it too technical to set up syncthing or similar, so finished film gets uploaded in the background while you take new one.
Instant screen lock is the most important I think, that way if the pigs come for you, just click the power button and your chances of keeping the vid are pretty solid. Oh, set “automatically backup over data” also, often by default it just does over wifi.
