From The Daily Signal:

According to a 2013 report by the Centers for Disease Control and Prevention, almost every major study on the issue has found that Americans use their firearms in self-defense between 500,000 and 3 million times a year. There’s good reason to believe that most of these defensive gun uses aren’t reported to police, much less make the local or national news.
For this reason, The Daily Signal each month publishes an article highlighting some of the previous month’s many news stories on defensive gun use that you may have missed—or that might not have made it to the national spotlight in the first place. (Read accounts from 2019 and so far in 2020 here).
