I never really realized I would ever have to explain this. But here it is… as short and quick as possible.

Constables, watchmen, or police have been around for thousands of years. Their job has generally been to support law and order in whatever town they work for. They protect all the citizens of the town.

In those towns that didn’t have them, rich people tended to hire private security of some kind using our modern parlance. Their job was to protect those who paid them and no one else.

If your town decides to get rid of the police, then there will be nobody to protect the common citizens of the town. While the rich people will hire private security and everything will be fine for them.

Hint. You don’t want to be one of the common citizens in this situation.
