I can think of a lot of such scenarios, especially if your phone is in your pocket (or off your person) and the cops yell "Hands up now or we shoot!".
You seem to be assuming you'll have lots of warning. Not always the case.
Yup...guess your fxxxxd all right. Damn Apple, how could they do this to me. Have you considered a Samsung phone, cheaper so you don’t loose as much at each arrest when phone is confiscated. Or how about carrying a burner phone. Buy em by the dozen, get discount. You could keep fake stuff on em as well, really send police off in wrong direction. Don’t mean to go off topic, but you seem quite concerned about arrest. You work at the White House? Just asking.
