US breaks record for most mass shootings in single year after weekend murders

Yeah, this is a horseshit article. They chose to define a mass shooting as an incident where 4 or more people are killed (excluding the shooter) rather than where 4 or more people are shot as they do in your gunviolencearchive.org link. Gunviolencearchive.org current;y has 25 incidents per page and is now onto page 26! It lists 631 mass shootings this year! This is day 338 of 2023 so that is 1.9 mass shootings per day! And it's not even an exhaustive list. It doesn't yet include, for example, the two mass killings listed in OP's article.

I mean... when no one else is competing, how hard is it to keep breaking your own records?

If you pay Guiness enough, there can be.

The article uses the term “mass killing”, so no.
