There are obvious ethical problems with a private security service supplanting the police. However this is an interesting example of how it might be advantageous to have multiple service providers competing in a market that try to be more efficient and provide more for less money. Maybe there should always be multiple police forces that compete in the same market. It might help get rid of violent cops who driving down the services reviews :-)
