Using FBI data (1992), homicide trends in the 17 states with less restrictive CCW laws compare favorably against national trends, and almost all CCW permittees are law-abiding.

Since adopting CCW (1987), Florida's homicide rate has fallen 21% while the U.S. rate has risen 12%. From start-up 10/1/87 - 2/28/94 (over 6 years) Florida issued 204,108 permits; only 17 (0.008%) were revoked because permittees later committed crimes (not necessarily violent) in which guns were present (not necessarily used).

Of 14,000 CCW licensees in Oregon, only 4 (0.03%) were convicted of the criminal (not necessarily violent) use or possession of a firearm.

Americans use firearms for self-defense more than 2.1 million times annually.
