Aggression and violence in the United States remain vexing problems that require several key responses. First, universal prevention programs and targeted treatment strategies for people at risk of aggressive behavior are needed to address the established link between mental illness and the potential for violence. Sadly, many perpetrators of gun violence are themselves victims of mental illness who find it all too easy to obtain and use firearms (Freedenthal, 2007). Efficacious interventions that break the potentially dangerous relationship between violence and mental illness should be a public policy priority. Finally, in an effort to find legislative solutions to regulate firearms effectively, lobbying efforts aimed at sane gun control policies must be a public policy priority. Social work's presence in these efforts should be continued and enhanced.
