Most defensive gun use (DGU) don't result in a shooting, much less death of the aggressor(s). Because most bad guys retreat at the mear sight of victim presenting firearm. To compare the death number between homicide with gun and justifiable homicide is disingenuous. http://en.wikipedia.org/wiki/Defensive_gun_use
Estimates over the number of defensive gun uses vary, depending on the study's population, criteria, time-period studied, and other factors. Higher end estimates by Kleck and Gertz show between 1 to 2.5 million DGUs in the United States each year.[1]:64–65[2][3] Low end estimates cited by Hemenway show approximately 55,000-80,000 such uses each year. Middle estimates have estimated approximately 1 million DGU incidents in the United States. The basis for the studies, the National Self-Defense Survey and the (Department of Justice) National Crime Victimization Survey (NCVS), vary in their methods, time-frames covered, and questions asked. DGU questions were asked of all the NSDS sample. Due to screening questions in the NCVS survey, only a minority of the NCVS sample were asked a DGU question. Besides the NSDS and NCVS surveys, ten national and three state surveys summarized by Kleck and Gertz gave 764 thousand to 3.6 million DGU per year. Hemenway contends the Kleck and Gertz study is unreliable and no conclusions can be drawn from it. He argues that there are too many "false positives" in the surveys, and finds the NCVS figures more reliable, yielding estimates of around 100,000 defensive gun uses per year. Applying different adjustments, other social scientists suggest that between 250,000 and 370,000 incidences per year.
About the Harvard studay by Michael Monutreaus. At first, the article was about gun ownership causing violent crime. Then it shifts back and forth between that, and claiming that more guns cause more gun related crimes.
You can find plenty of statistics that show higher gun ownership rates correlate with gun related crimes. Obviously, if you live in a state or country with an easy access to firearms, there will be more crimes committed with firearms. Human beings always seek out the most effective tools for the job, so they will always spring for best weapons they can get a hold of, regardless of whether or not they are criminals or law-abiding citizens.
But gun control advocates have a tendency to ignore overall homicides, and instead focus on homicides that are caused by firearms. When you do that, you’re missing the bigger picture. You’ll always fail to recognize that, while more guns equal more gun related crimes, they may also cause the overall violent crime rate to go down, a fact which has been proven time and time again.
The researchers behind the study admitted that while there did appear to be a connection between more guns and more crime, they weren’t sure which came first. Do guns cause more crime, or does a higher crime rate cause people to buy more guns?
Say it again: Correlation doesn't equal causation.
Also, this is but one study. There is another one says more guns doesn't mean more crimes. Your take?
Also, I have some difficulties believing that you trust data. Because if you do, you would fear driving more than guns. But after all, when you are in a small probability you-know-what with disastrous consequence, statistics is the last thing you want to think of.
