Is becoming a police officer in this day and age immoral? What kind of low life would be against the people who protect us day in an day out? I might be the one to tell you that being against an unaccountable monopoly isnt against the idea of safety nor security.
Unfortunately for police, legislation is not an exemption from morality. We must hold all accountable for their actions even government officials. However it seems impossible to do so because government investigates itself.
In order to properly give a service of any kind, there must be competition. This is because without competetion there is no incentive to provide the best service. That is why a monopoly on police, law and coercion ends up being immoral.
Police enforce laws that require violence to be used against peaceful people. Even worse cage them for extended times like animals. You can not be acting morally while caging innocents over orders given to you by a politician.
Police do not speak out against corruption, or unjust laws. If they do, they are usually killed , fired or publically smeared. This is not because of any other reason than the fact we are dealing with an institution of force and corruption.
For one to be morale they must not kill and extort others. Unfortunately we cannot say our police dont do that. Thousands of arbitrary laws with the sole intent of extortion. Some of these petty extortion tactics have even been the death of citizens.
If you are a cop, you are saying if necessary you will give a death sentence over even the most miniscule misconduct. You are not an agent of security, you are the iron fist of the state. To act with such blatent immorality and disregard for consent is seemingly delusional to do while also trying to claim to be a hero.
