> Pretty much every mass shooting by the colloquial definition makes the national news. I am unaware of any one that has not.
Now that sounds like obvious selection bias. Also, the Wikipedia article says "specifically for the purposes of this article, a total of four or more victims". But the point about the categorization is well taken. As the article says: "Many incidents involving organized crime and gang violence are included."
And this ‘mass shooting’ list also includes injuries NOT caused by shooting. What’s the point of that?
“ A man was killed and three women were injured when they fired upon in a vehicle on eastbound Roosevelt Road near Cicero Avenue in Cicero. The victims fled north onto Cicero Avenue into Chicago where they crashed, leading to three others being injured in the crash.[16]”
