Sheep can be controlled by the sheepdog for the same reason they fear the wolf -- they are both predators.  The same relationships hold with the general population, the police, and the criminals.  Most people are sheep, but you don't have to be.  If you have the skills and attitude of a predator the criminals will leave you alone -- because they will recognize you as a predator and there is easier game available.
