Okay, who will fulfill their role of policing, though?

When there's a crime committed and we need somebody answerable to the nation's laws in their actions, well trained to handle all situations safely, to go tackle/chase/fight the criminal, or rescue somebody from a criminal, who are we sending?

When they've been caught but need to be processed through the legal system, searched, questioned, charged with a crime, detained if needed for days or weeks, etc, all while ensuring that their legal rights and needs are being adhered to by the government branch that's got all these responsibilities, who are we sending?

I see a lot of people who call for the abolishment of all policing, such as yourself, but you might as well be suggesting we get rid of the Fire Brigade, or Teachers.

The Police are an essential service in any human civilisation, without which crimes would go entirely unpunished, criminals could do anything they want with impunity, there would be no law and safety, because the law is only as strong as those who enforce it. Society would collapse into chaos.

At best you'd have random disconnected groups of civilians banding together to enforce their own moral "law" on those they deem criminals, but they are unaccountable, unregulated, and no more than a lynching mob, even with good intentions.

I do of course agree that in some countries their police system is broken institutionally, and requires a complete reforming from the ground up. But that's a far, FAR stretch from suggesting the whole concept of policing the nation should be completely abolished. That way lies madness.
