Is the school police a policeman?

It is not the police, but the people established in the public security system. The police have the power to enforce the law.

What you say about "school police" is just another way of saying "safety"

Security guards can also question suspicious people when they see them on campus, and they can shoot when they steal or rob. This is not law enforcement! It is the duty of every citizen to stop criminal activities, which has nothing to do with law enforcement.

Actually, you may not understand what the police mean.

The police are all prepared and belong to the public security system.

For example, some fire brigades have non-active firefighters who are also firefighters, but they are not armed police, which is the same as this.

The easiest way to tell is to look at the clothes of the school police. Although it is very similar to the police, it is definitely different if you look at the epaulettes carefully. The public security system will not allow local security guards to have the same epaulettes as the police.
