Over the past several years, the HRWG has focused on different tracks, such as homicide data sets, characteristics of and relationships between victims and offenders, geographic distribution of homicide events, urban and national homicide trends, and specific factors that appear to be linked to homicide. The HRWG has also examined the identification of usable approaches to homicide reduction, the role of television in the production and reduction of violence, and the utility of a public health approach to violence reduction. Another topic considered regularly at HRWG meetings concerns the role of firearms in homicide events. The need to expand discussions on homicide to include contemporary biological and psychological theories of lethal violence is discussed. 4 references and 5 figures
