Exploiting spatial and temporal variations in the number of seizures from criminal organizations, I estimate regional fixed effects models of the increase in the number of properties confiscated on the main crime rates. From 2002 security strategies changed, and as a result, the effects on crime rates are mostly large, negative and significant. There was a clear reduction in crimes commonly committed by organized criminals, including guerrillas, paramilitaries and drug-traffickers, such as auto-theft, terrorism, terrestrial piracy, and kidnappings. In contrast, crimes usually committed by common criminals, such as street robberies and burglaries were unaffected by the new security policy.
