If the solution is satisfactory to both the shopkeeper and the thief, why should the effin’ government be involved?
Because we are a nation of laws. It is the proper place of government to protect the citizens from criminal acts. What if the solution isn't satisfactory? Should the merchant be able to amputate a right hand on the spot for the theft of a piece of bubble gum? A gold ring? What is just? The law provides a means to discern the magnitude of the offense and the proper punishment for the offender and restitution to the victim. What does the merchant do if the thief is part of organized crime that threatens to kill the merchant if the crime is reported?
