It is frequently said that it is “almost impossible to fire a police officer” because of protections afforded by civil service systems, collective bargaining agreements, state statutes governing the investigation of law enforcement officers, and the judicial doctrine of qualified immunity. This Article explores whether this assertion bears scrutiny, using previously published empirical studies and the more recent experience of a large metropolitan police department. The Article concludes that, despite the various protections against unjust discharge afforded police officers, they can readily be fired for misconduct if the employer conducts a reasonable investigation, gathers sufficient evidence to prove the misconduct, and complies with existing procedural rules. The Article describes reforms that employers may wish to consider to improve their ability to remove officers for good cause without unduly diminishing essential employee protections against unjust discipline, including harmless error rules, limiting arbitrator discretion over the form of discipline, preserving local government control over public policy, and increasing the scope of judicial review of arbitration decisions.
