For 21 years, Alvin L. Arnold served as a federal law-enforcement agent on the Canadian and Mexican borders. He arrested smugglers, confiscated marijuana, Cuban cigars, heroin and other drugs. Having removed what he thought was a significant amount of drugs from our streets, Arnold now sadly know he accomplished little beyond bringing a serious problem to the attention of a few caring people. In a letter to the editor for the Arizona Republic, Arnold now writes that he believes that the outlawing of marijuana is a waste of time.
