According to the National Crime Victimization Survey (NCVS) in 2000, victimizations involving a firearm represented 8% of the 6.3 million violent crimes of rape and sexual assault, robbery, and aggravated and simple assault.
The FBI's Crime in the United States estimated that 66% of the 15,517 murders in 2000 were committed with firearms.
Less than 1% of serious nonfatal violent victimizations resulted from gunshot wounds.
According to the 1997 Survey of State Prison Inmates, among those possessing a gun, the source of the gun was from -
a flea market or gun show for fewer than 2%
a retail store or pawnshop for about 12%
family, friends, a street buy, or an illegal source for 80%
During the offense that brought them to prison, 15% of State inmates and 13% of Federal inmates carried a handgun, and about 2%, a military-style semiautomatic gun.
On average, State inmates possessing a firearm received sentences of 18 years, while those without a weapon had an average sentence of 12 years.
Among prisoners carrying a firearm during their crime, 40% of State inmates and 56% of Federal inmates received a sentence enhancement because of the firearm.
A recent Justice Department study shows Americans own over 65 million Americans own roughly 225 million firearms.
As of 1995 there were over 240,000 machine guns registered with the BATF. About half are owned by civilians and half by police departments and other governmental agencies.
Since 1934, only one legally owned machine gun has ever been used in crime, and that was a murder committed by a law enforcement officer in 1988.
