The ethical nature of some crimes depends on circumstances, timing, and cultural context. Murder is a vile deed - but assassinating Saddam Hussein may be morally commendable. Killing an embryo is a crime in some countries - but not so killing a fetus. A "status offence" is not a criminal act if committed by an adult. Mutilating the body of a live baby is heinous - but this is the essence of Jewish circumcision. In some societies, criminal guilt is collective. All Americans are held blameworthy by the Arab street for the choices and actions of their leaders. All Jews are accomplices in the "crimes" of the "Zionists". In all societies, crime is a growth industry. Millions of professionals - judges, police officers, criminologists, psychologists, journalists, publishers, prosecutors, lawyers, social workers, probation officers, wardens, sociologists, non-governmental-organizations, weapons manufacturers, laboratory technicians, graphologists, and private detectives - derive their livelihood, parasitically, from crime. They often perpetuate models of punishment and retribution that lead to recidivism rather than to to the reintegration of criminals in society and their rehabilitation. Organized in vocal interest groups and lobbies, they harp on the insecurities and phobias of the alienated urbanites. They consume ever growing budgets and rejoice with every new behaviour criminalized by exasperated lawmakers. In the majority of countries, the justice system is a dismal failure and law enforcement agencies are part of the problem, not its solution. The sad truth is that many types of crime are considered by people to be normative and common behaviours and, thus, go unreported. Victim surveys and self-report studies conducted by criminologists reveal that most crimes go unreported. The protracted fad of criminalization has rendered criminal many perfectly acceptable and recurring behaviours and acts. Homosexuality, abortion, gambling, prostitution, pornography, and suicide have all been criminal offences at one time or another. But the quintessential example of over-criminalization is drug abuse. There is scant medical evidence that soft drugs such as cannabis or MDMA ("Ecstasy") - and even cocaine - have an irreversible effect on brain chemistry or functioning. Last month an almighty row erupted in Britain when Jon Cole, an addiction researcher at Liverpool University, claimed, to quote "The Economist" quoting the "Psychologist", that: "Experimental evidence suggesting a link between Ecstasy use and problems such as nerve damage and brain impairment is flawed ... using this ill-substantiated cause- and-effect to tell the 'chemical generation' that they are brain damaged when they are not creates public health problems of its own".
