“Journalists” love to theorize and pontificate, based on stuff they’ve read in places like Esquire. But home made explanations will never capture the essence of the problem. The fact remains that the mass shooter is exceedingly rare in a population of hundreds of millions of people. For any social explanation you can apply to a given shooter, there are hundreds of thousands, maybe millions, who match the picture precisely but never do harm to anyone.
This is why the popular game of “profiling” almost never gets anywhere. Remember the horde of “experts” who profiled the DC sniper. Very precise, but totally not accurate.
Ah, the angry middle aged white man in a white panel van. Thanks for reminding us.
