To be a decent person in a position of power is to be willing to resist your own duties
People who work as functionaries in a police apparatus, such as a psychiatrist at a public hospital, seem to be very resistant to recognizing, if not unable to do so, the possibility that their institution and its employees do things that are injustices. They may be very atrocious injustices, acts of great violence, that are completely unjustified.
Most such workers have no real moral integrity when it comes to the very possibility of any essentially political injustice. If they did have the true moral integrity that depends upon some kind of political consciousness other than one that is merely subservient to the system, then they would necessarily know that they must resist some of the things they are expected to do by their employers. This is my criterion for a decent person in such an occupation, and I think people subject to their power and authority should look for that, as a criterion of according them any kind of trust.
