>>>>Research shows that surprisingly often gun deaths are self-inflicted.
In 2005, the most recent year for which statistics are available from the Centers for Disease Control and Prevention (CDC), suicides accounted for 55% of the nation's nearly 31,000 firearm deaths.
In the same year, 40% of deaths were homicides, 3% were accidents and the remaining 2% were "legal killings", such as when police officers do the shooting in the course of duty.
Nor was there anything unique about that particular year. Gun-related have suicides outnumbered firearm homicides and accidents for 20 of the last 25 years, according to CDC statistics.<<<<
If there were this many US military casualties in a war ( say Iraq or Afghanistan) all of the voting population would be screaming for the US to get out. The big problem is that too many gun owners don;t use their guns for home protection but as a way to resolve differences.
