If you see the cops, start recording
Cops may ask you not to record and even threaten you with arrest for recording. Do not be intimidated; it is your right to record without obstructing.<p>If you find yourself in a situation where you might be detained and thereby unable to control interactions with your device, on iPhone you can disable TouchID and FaceID by holding one of the volume buttons and the sleep/wake button simultaneously for a few seconds. This will require you to enter your passcode the next time you want to unlock iPhone. Anyone have similar instructions for Android?
