From Breitbart:

A Congressional Research Service (CRS) report shows that while gun ownership climbed from 192 million firearms in 1994 to 310 million firearms in 2009, crime fell—and fell sharply.

According to the report, the “firearm-related murder and non-negligent homicide” rate was 6.6 per 100,000 Americans in 1993. Following the exponential growth in the number of guns, that rate fell to 3.6 per 100,000 in 2000.

And keep in mind that — aside from the 10-years when the so-called “assault weapons” ban was in effect — a whole lot of states loosened their gun laws to allow (shall issue) CCW, among other things.
