There have been conservative estimates ranging from 100,000 DGUs (defensive gun uses) to 350,000 per year. Let's use 100,000. There are 318 million people in the United States. Let's pretend they're all adults. That would mean 3 out of every 10,000 people in the US use a firearm defensively each year. Looks unimpressive, right?
Wait.
There are only 80,000,000 estimated gun owners in the US, which means that only 80,000,000 US citizens COULD use a firearm defensively. Still assuming the 100,000 number, we now have 1 out of every 1,000 owners using a firearm defensively each year.
Wait.
There are around 9,000,000 total concealed carry licensees in the US, and only a few states where people carry without a license. To account for off duty LEOs, we'll add 1 million carriers. To account for people with multiple CHLs, let's subtract 500,000. Of the 7.5 million non LEOs, let's assume a HIGH estimate of 33% actually carrying each day. 2.5 mil plus 1 mil equals 3.5 million carriers -- roughly a pool of 1% of the US population, who could use a firearm defensively outside of the home.
So, using intentionally conservative estimates, we have:
About 318,000,000 potential victims suffering 440,000 gun crimes. That's 1:1,000 victimization rate.
vs 1:1000 owners with DGUs each year...
...and that doesn't account for the slant that would result if we found a way to account for the number of violent crimes that take place outside the home, which reduces the pool of possible DGUs.
While this is all estimation, I have been conservative at every point, and the rate of DGU exceeds the rate of victimization, when accounting for possible victims and possible defenders.
I'm sure there are people who could do this far more justice than I could. I am simply amazed that I have never seen DGUs expressed as a rate among those who could possibly effect them.
Do I think it's actually practical to carry? Well... Yeah. One of those DGUs was me.
