THE STUDY WAS DESIGNED TO IDENTIFY THE PERCEIVED DRUG PROBLEMS OF THE URBAN NARCOTICS UNITS INVESTIGATED OVER A 1 1/2 YEAR PERIOD, TO DETERMINE THE GOALS AND OBJECTIVES OF THE UNITS WITH RESPECT TO THAT DEFINED ENFORCEMENT PROBLEM, AND TO GATHER FROM OFFICIAL RECORDS, INTERVIEWS, AND OBSERVATIONS THE SPECIFIC MEANS AND STRATEGIES USED TO ACHIEVE THESE GOALS. ONCE THIS MODEL OF THE ENFORCEMENT PROCESS WAS ARTICULATED, THE RESEARCHERS SOUGHT TO DETERMINE HOW THE ORGANIZATION STRUCTURE MAINTAINED CONTROL OVER EVIDENCE, MONEY, INFORMANTS, AGENT REQUIREMENT, AND AGENT TRAINING. IT WAS FOUND THAT NARCOTICS ENFORCEMENT ACTIVITIES ARE INVESTIGATOR CENTERED RATHER THAN ORGANIZATION CENTERED, A FACT WHICH AFFECTS ACTIVITIES SUCH AS DUAL SETTING, BUDGETING, RECORDKEEPING, TARGETING STRATEGIES, AND THE USE OF INFORMANTS. IT IS ARGUED THAT ORGANIZATIONAL CAPACITY TO CONTROL THE ACTIONS OF INVESTIGATORS RESULTS IN AN INCREASED CAPACITY TO ACHIEVE GOALS AND OBJECTIVES.
