Mental health gets trotted out when the rational behind it seems to be non-senseical, random, or otherwise “crazy”.
A criminal shooting another criminal or a robbery victim isn’t something that people are at least understanding of their motives. Regardless of color.
Random mass shooting for no obvious reason and most people conclude there must be something mentally wrong with them. Regardless of color. It just seems that POC commit less mass shootings. Or maybe they just don’t make the news due to media bias. I bet none of you heard about this, but I did because I have friends who live in/near Heston.
The guy who shot two former co-workers while they were on site, Vester Lee Flanagan II/Bryce Williams was also a POC and characterized as mentally ill.
The Belt-Way shooter (POC) had a mix of both mental illness, master manipulator, lone-wolf terrorism, and methodical murderer.
So I think a blanket statement like that is neither accurate nor helpful.
I will say also that mental health certainly plays into SOME murders, but not the vast majority. The problem is everyone wants to do SOMETHING when something bad happens. They want to lay blame on SOMETHING when something doesn’t make sense.
