If you're going to bandy numbers about, perhaps you could actually read the report that you cite as your evidence. The 2.5 million defensive gun uses (DGU) number does not come from the Justice Dept, but was the result of a telephone survey conducted by an academic that is cited in the DOJ report. The DOJ report itself calls this number into question, as well as the result of their own survey that used a similar methodology and gave an estimate of 1.5 million DGUs. There is yet another estimate from the Bureau of Justice Statistics National Crime Victimization Survey (NCVS) that puts the number at only 108,000 DGUs per year. The DOJ report said:

Private citizens sometimes use their guns to scare off trespassers and fend off assaults. Such defensive gun uses (DGUs) are sometimes invoked as a measure of the public benefits of private gun ownership. On the basis of data from the Bureau of Justice Statistics National Crime Victimization Survey (NCVS) data, one would conclude that defensive uses are rare indeed, about 108,000 per year. But other surveys yield far higher estimates of the number of DGUs. Most notable has been a much publicized estimate of 2.5 million DGUs, based on data from a 1994 telephone survey conducted by Florida State University professors Gary Kleck and Mark Gertz.[13] The 2.5 million figure has been picked up by the press and now appears regularly in newspaper articles, letters to the editor, editorials, and even Congressional Research Service briefs for public policymakers.

The NSPOF-based estimate of millions of DGUs each year greatly exaggerates the true number, as do other estimates based on similar surveys.

So the survey you cite as your evidence states that the estimate of 1.5 million DGUs per year "greatly exaggerates" the true number. And the number you gave (2.5 million) is one million more than that. The more accurate estimate (for various reasons if you care to actually read the report you cited) is 108,000 DGUs per year. Anyway, good job. To quote your earlier reply,
