If I don't trust my doctor, I can ignore them and find a new doctor.

If I don't trust my therapist, I can ignore them and find a new therapist.

If I don't trust my housekeeper, I can fire them and hire a new housekeeper.

If I don't trust a police officer, it doesn't matter. If they detain me and order me to step out of my vehicle, I have to comply under threat of the law and violence. I don't get to only listen to police officers whom I trust.

That is why they must be held to a higher standard, because they wield elevated authority not granted to ordinary citizens.

A police officer who has demonstrated such a reckless disregard for the law and safety can not be trusted as a police officer to uphold the law.
