After more than 30 years of death, destruction, and failure, the two primary advocates of the war on drugs are public officials and drug lords. The reason is obvious: these two groups are the biggest beneficiaries of the drug war. The drug lords make money off the war — big money. And government officials make money off the war — big money.
One of the major ways that government officials make money off the drug war is through bribes. Government inspectors at international crossing points are bribed to look the other way when a drug shipment is coming across the border. Drug agents are bribed to look the other way with respect to drug distribution. Prosecutors and judges are bribed in return for reduced sentences.
