Radley Balko and other libertarians repeatedly make maudlin appeals bemoaning the supposed injustices of long prison sentences and rough police tactics used against drug dealers.

But the problem with libertarians’ abstract appeals to liberty in this case is that people with real experience with drugs and drug dealers know two things that libertarians dismiss all-too-casually: (1) drugs–particularly hard drugs like cocaine, meth, and heroin–often make good people do bad things, and (2) drug dealers are generally violent, deceitful, selfish, and antisocial people that harm their communities.

Drugs are uniquely bad in this regard. Other criminal types of behavior–auto theft, white collar crime, shop lifting, tax evasion–do not turn their purveyors into murderous, rampaging psychopaths. Yet violence and the drug trade go hand and hand. One needn’t look very far to find evidence that drug dealers are more violent than law-abiding people, often remarkably so.

In response, the libertarians would tell us that these people wouldn’t be violent, but for the criminalization of drugs. This doesn’t make logical sense. Other things are illegal, and other people commit crimes, yet they do not become violent. Further, there is evidence that the intensification of the drug war and the increased use of mandatory sentences for drug offenses were significant factors in the decade-long drop in violent crime during the 1990s. Surely some of the people being locked up on drug offenses would have committed violent offenses that are much harder to detect and prove than something like drug possession.

In other words, the drug laws are a large and somewhat overinclusive net in which so many pathological and anti-social people can be collected. In this milieu, the police, instead of having to investigate harder-to-prosecute violent crime offenses, can do a lot to stop violent crime by arresting and prosecuting drug offenders.

Until libertarians recognize that drug dealers are not simply good people doing something technically illegal, but rather bad peope exhibiting one of several criminal tendencies when they deal drugs, their maudlin attempts to “humanize” drug dealers and reduce penalties for drug dealing will be seen as naive and a bit offensive to most Americans, particularly inner-city and poorer Americans who must live among these predatory people.
