American libertarian Alan Bock at Antiwar.com:
The most efficacious approach [.pdf] to stemming the violence in Mexico is to recognize that just as what most newspapers blithely call “drug-related crime” is actually drug-law-related crime or even drug-law-caused crime, the wave of violence in Mexico is not caused by the inherent viciousness of the Mexican underclass or the physiological properties of drugs deemed illicit, but by the set of perverse incentives that arise when governments treat adults like children and dictate what they can ingest, attempting to prohibit plants and substances that are easily grown and formulated and for which there is a steady demand. The violence in Mexico is not “drug-related” but “drug-law-related” or even caused directly and indirectly by the laws attempting to prohibit the use of some substances.
While I do not agree with the moral aspects of Bock’s approach – which attribute the moral failings of individuals to government policy – and place the moral blame for these actions on the government – his policy analysis here strikes me as fundamentally sound.
