No, it's actually one of the most problematic points in anarchist theory. How to handle people who are cruel or who do not respect social contracts. The fact that many anarchists want to abolish police but than want to build a structure similar to police or do not discuss the topic at all is showing they don't have a solution.

Stirner for example basically ignores the topic. Kropotkin only addresses crimes which have the state as basis (property and political crime).

Please share which Anarchist theoretist formulated a concrete plan on how to deal with non-political crime in practice.
