the definition of mass shooting changes from agency to agency.

mother jones, for instance, shows only 6 mass shootings in 2021.

if you change the rules to include gang-related shootings or family shootings, black "shooters" end up the majority. this is simply based on numbers, considering "black" shootings make up 60%+ of all homicides in the USA.

most of this data is available from the FBI.

the interesting part is that white male suicide is such a huge number as well.

something like 40k gun deaths with 60% being white male suicide and 9k of what is left being black-on-black homicide.
