As far as statistics to back up my claim:
The finding of 1.5 million yearly self-defense cases was published in Philip J. Cook and Jens Ludwig, "Guns in America: National Survey on Private Ownership and Use of Firearms," National Institute of Justice Research in Brief (May 1997);
The finding that citizens use their guns to defend themselves 2.5 million times every year was published in "Armed Resistance to Crime: The Prevalence and Nature of Self-Defense With a Gun," Gary Kleck and Marc Gertz, " 86 The Journal of Criminal Law and Criminology, Northwestern University School of Law, 1 (Fall 1995) pp. 173, 185.
The fact that "States which passed concealed carry laws reduced their murder rate by 8.5%, rapes by 5%, aggravated assaults by 7% and robbery by 3%" was published by
John R. Lott, Jr., "More Guns, Less Violent Crime," The Wall Street Journal (28 August 1996). See also John R. Lott, Jr. and David B. Mustard, "Crime, Deterrence, and Right-to-Carry Concealed Handguns," University of Chicago (15 August 1996); and Lott, More Guns, Less Crime (1998, 2000).
FBI reports show that the homicide rate in Florida, which in 1987 was much higher than the national average, fell 52% during that 15-year period -- thus putting the Florida rate below the national average.
U.S., Department of Justice, National Institute of Justice, "The Armed Criminal in America: A Survey of Incarcerated Felons," Research Report (July 1985): reported that:
3/5 of felons polled agreed that "a criminal is not going to mess around with a victim he knows is armed with a gun."
74% of felons polled agreed that "one reason burglars avoid houses when people are at home is that they fear being shot during the crime."
57% of felons polled agreed that "criminals are more worried about meeting an armed victim than they are about running into the police."
Do those "back up" my claims?
