According to psychologists, there is a personality trait called neuroticism. Neurotic people worry about everything. They worry about getting sued. But they also worry about whether they look fat in these clothes, whether they will forget their uncles birthday, 5g radiation, microplastic partles in the air and whether the guy on the ground is dying or not.

What I'm hinting at is that a neurotic police force would be less likely to harm people. But also take less action in general, solve less crime.
