One such environmental criminology approach was developed in the 1980s, by Paul and Patricia Brantingham, putting focus of criminological study on environmental or context factors that can influence criminal activity. These include space (geography), time, law, offender, and target or victim. These five components are a necessary and sufficient condition, for without one, the other four, even together, will not constitute a criminal incident. Despite the obvious multi-faceted nature of crime, scholars and practitioners often attempt to study them separately. For instance, lawyers and political scientists focus on the legal dimension; sociologists, psychologists and civil rights groups generally look to the offenders and victims, while geographers concentrate upon the location of the event. Environmental criminologists examine the place and the time when the crime happened. They are interested in land usage, traffic patterns and street design, and the daily activities and movements of victims and offenders. Environmental criminologists often use maps to look for crime patterns, for example, using metric topology.
