It isn’t about trust, it is about how likely you are to encounter a risk and how big that risk, if encountered, is. Do you own a hazmat suit? A nuclear bunker? Did you install a 5-point harness and wear a helmet when you drive? Could you be tortured for information by the police? Yes. Is that in any way likely at all? No. Taking reasonable precautions against likely actions by law enforcement is better than acting like all things are possible so no point in doing anything.
The chance of encountering a police that operates unlawfully - especially since they have qualified immunity is a very big risk. The chance of other police covering for them is close to 100%

Probably, most people don’t see rubber hose cryptography as a real threat, and in most cases, they’re probably right.
