Nope.

If you want to know what kind of people will be in a job, on average, consider what the job incentivizes and how that might appeal to the motives of different kinds of people.

Law enforcement ostensibly promotes an image of community service and protection. So you will find people that wish to do those things seeking to become police officers.

But the reality is that police work itself, policies, and legal protections for officers is far more focused on the state sanctioned use of force, the strict adherence to laws for citizenry but far more lax enforcement on officers themselves, and the authority of command given to officers in interactions with them. So for someone who wants to posture as a tough guy, to dominate over people with legal authority, to commit acts of violence with little, if any, consequence for themselves or recourse for he victim, and to remain in good standing in much of society because of the aforementioned promoted image, it serves those desires too.

And due to the us vs them mentality, the lack of liability, and the tight community formed just within law enforcement and those who work directly with them (prosecutors/DAs, judges, mayors, etc) that do not hold each other accountable unless they do something to violate that community (like reporting abuse of authority, excessive force, gross negligence, etc. on fellow officers), then the police culture itself incentives pushing out the cops with good intentions that may stir up "trouble" in the community in favor of those who will allow or actively propagate corruption and collusion.

If a job incentivizes and/or protects aggression, violence, and pretty crime, don't be shocked when it's full of aggressive, violent, petty criminals.

Perhaps, Japan...

That's how they got the job.

Nowhere that has hierarchy, and therefore power and wealth held in the hands of a few to pay others to commit violence on their behalf.

But who are the police and the soldiers who protect the capitalists against you, against the people?

If they were capitalists themselves, then it would stand to reason why they want to protect the wealth they have stolen, and why they try to keep up, even by force, the system that gives them the privilege of robbing the people.

But the police and the soldiers, the defenders of ‘law and order’, are not of the capitalist class. They are men from the ranks of the people, poor men who for pay protect the very system that keeps them poor. It is unbelievable, is it not? Yet it is true. It just comes down to this: some of the slaves protect their masters in keeping them and the rest of the people in slavery. In the same way Great Britain, for instance, keeps the Hindoos in India in subjection by a police force of the natives, of the Hindoos themselves. Or as Belgium does with the black men in the Congo. Or as any government does with a subjugated people.

It is the same system.

Here is what it amounts to: Capitalism robs and exploits the whole of the people; the laws legalize and uphold this capitalist robbery; the government uses one part of the people to aid and protect the capitalists in robbing the whole of the people. The entire thing is kept up by educating the people to believe that capitalism is right, that the law is just, and that the government must be obeyed. Do you see through this game now?
