That's not really the point. Innocent people have the right to not have their things searched and dug through. Every person has some level of privacy that they want to keep. Let's say you have nudes from your significant other and yourself all over your phone. You don't want that information being seen by anyone else because it was meant for you and you alone. I guarantee your partner doesn't want random people seeing them either.

It is well known there have been bad actors in the IT and police that will make copies of that for their own personal use while they are supposed to be doing something else. Would really want to risk that?
