Our purpose here is not to attack or put down the police or their departments. While it’s true that there are both good-guys and bad-guys, that’s true about all humanity.
Rather, this post, and many others to follow, are to help folks understand how things will work without government, IOW when we have a truly Voluntary System.
Most everything is based on the primary Principle; Sovereign Individuals (everyone) have first the Right to Life, Liberty, Happiness, Property and Prosperity. Along with that necessarily includes the right and responsibility of Protecting that essential basic Right.
The first line of that protection is Self-Defense, which of course does not extend to intruding upon these same and “equal” Rights of anyone else. The expense of whatever means used to self-defend are not paid by government taxes and edicts, but by the sovereign individual in accordance with his own best judgement and ability. As no government exists, there are no “taxes” for anything, thus humans have all of their own resources to acquire whatever they might want.
Beyond that would be actions such as “Neighborhood Watch”, a voluntary and unpaid effort of people who care and loosely band together to accomplish. Similar, but at some cost, are gated subdivisions with varying levels of security. Some may have only a key or gate-code, while the best security would include securely fenced perimeters, armed gate-guards, and who knows what else!
Yet another alternative to government police is simply retaining a Private Security Company, using the money which no longer is usurped by government taxation. Perhaps some danger exists that such Private Security Company might turn to behaving like Mafioso, but such companies in a free market should be quickly competed out-of-business, ya’ think? Surely this covers only the edges of the issue, so feel free to comment to add more!
