Violence Against Police: Baltimore County, Maryland, 1984-1986 (ICPSR 9347)
Principal Investigator(s): Uchida, Craig D.; Brooks, Laure W.
This data collection examines individual and situational characteristics of nonfatal assaults on police officers in the Baltimore County Police Department. In the assault data, variables include: (1) information on the officer such as age, race, sex, height, weight, education, rank, assignment, years of experience, weapon, and injury sustained, (2) information on the offender(s) such as age, race, sex, height, weight, weapon, injury sustained, and arrest status, and (3) information on the actual situation and incident itself, such as type of call anticipated, type of call encountered, type of location, numbers of persons present (by role, e.g., assaulter, nonassaulter, complainant, etc.), type of initial officer action, actions of suspect before assault, sobriety/drug use by suspects, and final disposition. The calls for service data were collected to provide an indication of the frequency of various types of calls. In these data, variables include time of call, initial call category, disposition code, and sheet ID.
