EH? There are mountains of statistics that show this. Here's one, from the decidedly non-gun friendly CDC, that was commisssioned and then ignored by President Obama that summarized thusly
"As to defensives uses of guns, the CDC report said, "Studies that directly assessed the effect of actual defensive uses of guns (i.e., incidents in which a gun was 'used' by the crime victim in the sense of attacking or threatening an offender) have found consistently lower injury rates among gun-using crime victims compared with victims who used other self-protective strategies. ... Almost all national survey estimates indicate that defensive gun uses by victims are at least as common as offensive uses by criminals, with estimates of annual uses ranging from about 500,000 to more than 3 million per year, in the context of about 300,000 violent crimes involving firearms in 2008."
