How many government organizations (especially unionized ones) get rid of or otherwise deal with bad performers? Instead of pointing out the military as the rule and police officers as the exception, maybe we should consider that the military is the exception. Teachers, federal employees, and government employees at all levels of local government are known for being able to keep their jobs long after they should have been fired or disciplined. The egregiousness of bad policing is that many times they are breaking laws. But honestly, there are gray areas. The police are allowed to hit some people. They have to shoot some people. So it's not a huge leap to assume that some of them will overstep their bounds. And when they do, the union will back them, and their colleagues will back them. And we'll hear how underpaid they are (just like teachers). And they keep their jobs, just like bad teachers.
