Oh, gee, more subjective interpretations, what a surprise. First, where is your evidence that the surveys are done by phone and not gathered from crime stats. The stats I originally cited are from FBI statistics from 1992, a tidbit you conveniently ignored.
If you want to talk about flawed studies, look at the NCVS.
"was not designed to estimate how often people resist crime using a gun. It was designed primarily to estimate national victimization levels; it incidentally happens to include a few self-protection questions which include response categories covering resistance with a gun. Its survey instrument has been carefully refined and evaluated over the years to do as good a job as possible in getting people to report illegal things which other people have done to them. This is the exact opposite of the task which faces anyone trying to get good DGU estimates--to get people to admit controversial and possibly illegal things which the Rs themselves have done. Therefore, it is neither surprising, nor a reflection on the survey's designers, to note that the NCVS is singularly ill-suited for estimating the prevalence or incidence of DGU. It is not credible to regard this survey as an acceptable basis for establishing, in even the roughest way, how often Americans use guns for self-protection."
Of course, the only thing you'll pick out of that quote is "possibly illegal things".
I'm not saying you were nitpicking, I was asking you to do something statistically valid, which was throw out the highest and lowest numbers given from the 13 surveys referenced on the GunCite page. That yields about 1 million legit DGUs per year. Do you disagree?
And your statement about appropriate degree of force is hugely subjective and a big assumption. And I've seen numerous other studies the NRA has referenced, not just Kleck's.
And another thing, why is less than 10%(assuming the 2.5 million figure is accurate) of the US population defending themselves with firearms so unbelieveable? That leaves more than 295 million Americans NOT using guns to defend themselves.
