Adam, I agree with you that a lot of things that are considered crimes should not be crimes but I also agree with the detractors of private security claiming a “two-tier” system would be created. Evidence of that can be found back in history with the quality of services in a system of “separate but equal” services. They will not remain equal as private economic forces play-out in the long run. That said, private police forces that are forced to follow ethical standards of proof and evidence standards are most definitely going to be more efficient. Not necessarily more fair towards poor people and eventually corruption of evidence is more likely in a judicial system with and underlying profit motive.
