The case of brutality may be even simpler to resolve. Granting police special status before the law gives them a greater incentive to violate the rights of others than the average citizen would have. Were courts to strip the police of their sovereign immunity, police brutality would be nothing more than instances of injustice that the courts could correct. Police misconduct is spectacular not only because of its prevalence, but also its far greater potential for harm than other forms of crime. Yet these differences should not lead one to believe that police crime is any more inevitable than other forms of crime.
Police react to free market incentives, just like everyone else.
The trick is lining up the incentives to prevent crime instead of causing it.
