> This is not the role of the police. Their role is solely punishment and deterrence. Wrong. The role of the police is to enforce the law. If the law says you are not allowed to be in possession of certain substances that you are in possession of, then you have committed a crime and the police can arrest you for it. End of story. > Passing a law against drug use is pre-crime when the only real justification for the law is to prevent other crimes. It is not pre-crime. By definition, pre-crime is arresting someone before breaking the law. If possession/use is illegal and you do either of those things, you have committed a crime. I repeat: You have already committed a crime if you use/possess illegal drugs. It cannot be pre-crime in such a scenario. Also, it's perfectly reasonable and practical to make something illegal because it leads to other (more damaging) actions.
