Which more often than not includes being safe from the police, and that's where the problem lies. This sort of power is bound to be abused.

Interesting. I've lived in places where unlocked doors were the norm, the village where I live (20 Km from Amsterdam) still has plenty of unlocked doors. People wear safety belts because there are no downsides and because they are required by law so that stretched analogy doesn't hold.
