While community violence in the United States has diminished since the early 1990s, when its levels peaked to epidemic proportions, it continues to be a major public health problem. Indeed, over the course of the last decade, American teens and young adults have continued to experience rates of violent crime that are much higher than those for any other age group (Bureau of Justice Statistics, 2007). According to the Centers for Disease Control and Prevention (CDC, 2009a, 2009b), in 2006, 5,958 young people between the ages of 10 and 24 were murdered, making homicide the second leading cause of death for youth in that age group. Additionally, in 2007, more than 668,000 young people aged 10–24 years were treated in emergency departments for injuries sustained from violence.
