People who utilize a structured society, not a roving band of city-dwelling mercenaries? There are many, many examples of bands of 'citizens' subverting the legal system by taking justice into their own hands. Often, they ended with lynchings. We have police and a government because the protection of the people is the job of professionals who (usually) respect the rule of law, not random able-bodied men hunting down (possibly innocent) people through city streets.
