Once people are given the right to punish or to threaten punishment by the state, they are no longer required to interrogate themselves and can fall back on convenient dehumanized views of the people they want to hurt.

This is why some people feel righteous in calling the police instead of facing their own anxieties, and why others reinforce them in this terrible decision, or even worse: they stand by and do nothing.
