Going by your stats….
Whites are 62% of the population and commit 60% of the mass shootings. Statistically it is about the same percentage as the population.
Blacks are 12% of the population yet commit 18% of mass shootings. That is 50% higher than their population.
So by your stats, Blacks are 50% more likely to commit mass shootings based on race.
Based on population, which is what I said in my previous comment, Whites committing the most mass shootings is a myth.
Thanks for your own statistics proving my point.
