The article attempts to illuminate the range of beliefs, perceptions and attitudes of law enforcement officers responsible for dealing with public health issues on a daily basis. Subjects (n=142) were asked to complete the Law Enforcement and AIDS Survey, a series of 54 questions in six specific areas: (1) subjects' primary sources of HIV/AIDS information and accuracy of their knowledge regarding major modes of exposure; (2) subjects' HIV/AIDS-related, profession-specific training and access to protective devices; (3) perceived adequacy of departmental policies guiding subjects' behavior in potentially infectious situations; (4) frequency of exposure to the virus, practical measures to diminish risk of contagion, and perceived levels of psychological concern; (5) subjects' personal history of HIV testing; and (6) changes in subjects' behaviors and perceived ethical responsibilities precipitated by fear of contagion.
