Gun advocates call it DGU. The initials stand for Defensive Gun Use. Gun proponents claim that such incidents – homeowners using guns to protect themselves against intruders – are extremely common, and that we don’t work hard enough to include them in the Gun Report. (A reminder: we compile this daily report by typing “shooting” into Google News and looking at gun injuries and deaths from the past 24 hours. We don’t “favor” any form of gun violence over any other form.) In any case, today we have three examples of DGU, along with one example of a 3-year-old shooting himself by accident. It is unclear whether the gun the child used was owned by someone in his home, but we have our suspicions.

Here is today’s Gun Report.
