The DEA, with agents stationed in most Latin American countries, has offered a hands-on complement to the State Department's diplomatic efforts in dealing with drug-related corruption in Latin American countries. The DEA's ability to counter corruption in any country is influenced by the nature and scope of the corruption, particularly the extent to which it is condoned or tolerated by top officials. One strategy for circumventing corruption is for DEA agents to develop special relationships with a few local agents rather than depending on the foreign agency as a whole to conduct investigations. Since there are so few local agents who can be trusted or maintained, however, the DEA has little choice but to work with corrupt agencies and agents. One of the most successful measures has been the creation of elite drug enforcement units composed of local police. DEA agents are active in creating these units, often training them, handpicking their heads, and overseeing their hiring, as well as working closely with them in all aspects of their operations. 13 notes, 29 references.
