According to a Congressional Research Service report released on Nov. 14, 2012, the gun homicide rate in the United States dropped from 6.6 per 100,000 to 3.2 per 100,000 from 1993 to 2011. The number of accidental gun deaths dropped from 1,521 in 1993 to 554 in 2009. The number of firearms related homicides for juveniles dropped from 1,975 in 1993 to 887 in 2009. The number of accidental gun deaths for juveniles dropped from 392 in 1993 to 83 in 2009.
All this happening at the same time that the number of guns has increased, and the number of individuals licensed to carry concealed firearms has increased.
Of course, this does not mean the increase in guns and concealed weapons permits CAUSES a decline in the gun homicide rate. But those increases certainly do not seem to cause any increase in gun homicide rates. More guns do not equal more gun crime.
