Murderers, thieves, rapists and drug dealers walk freely among us. We count on the police to do the best they can to catch as many of these people as possible, but do not expect that every case will be solved nor every criminal apprehended. The best we can hope for is that those that are caught, whether by their own carelessness or by diligent police work, are brought to justice. For this reason we encourage the police to engage in crime fighting as a competitive and adversarial enterprise.
