If the matters can go to that violence, you have bigger problems that somebody playing candy crash with your phone...

It can always go to that, due to nothing you’ve done.

Mistaken identity, planted evidence (from someone else, like drugs put in your bag by a handler for picking up by a compatriot in the destination, but caught before then, or by bored police!), political targeting (like you’re the ‘wrong’ nationality, and the country you’re traveling to wants some leverage), etc.

Muggers or bandits also don’t exactly ask if today is a good day either.

If the worst violence to fear in police custody is being held straight so that your phone can be pointed at your face I'd say you're quite safe...

I mean you have got a point. Forces serving governments are known to kill innocents in cold blood, and commit plenty of genocides, so yeah…

I have nothing to hide, but I travel with a secondary phone that I wipe before crossing international borders, to which I’ll happily give law enforcement access.
