"Suicides accounted for 55 percent of the nation's nearly 31,000 firearm deaths in 2005, the most recent year for which statistics are available from the Centers for Disease Control and Prevention.
There was nothing unique about that year - gun-related suicides have outnumbered firearm homicides and accidents for 20 of the last 25 years. In 2005, homicides accounted for 40 percent of gun deaths. Accidents accounted for 3 percent. The remaining 2 percent included legal killings, such as when police do the shooting, and cases that involve undetermined intent."
