Law enforcement officials, experts in public health, criminologists, educators, and youth offered testimony intended to help Congress understand the scope of the threat of guns and firearm violence to young people and the strains of the firearm problem on public and community services. A fact sheet points out that: (1) increasing numbers of youth are killed by firearms; (2) guns in the home are more likely to be used to kill residents than guns of intruders; (3) guns, mostly handguns, are used in the majority of youth homicides; (4) guns are used in most youth suicides; (5) youth bring guns to school with increasing frequency; (6) gunshot injuries of children are increasing and burdening the health care system; and (7) firearms are more deadly than other weapons in assaults and suicides. The report provides data tables on trends in firearm violence among the young and firearm production by U.S. manufacturers 1973-85, and a paper by Gary Kleck, "Policy Lessons from Recent Gun Control Research."
