You're mistaken, as I was simply trying to draw attention to the fact that the motivations, and therefore salves, for a) a mass shooter who enters a soft target and kills strangers indiscriminately, and b) a "mass shooter" who knows his target and catches innocents in the crossfire, differ substantially. You group the two in order to dilute the focus of anti-gun violence advocacy, but you're given away by how little you care about instances of the latter definition otherwise. If "mental healthcare" is your panacea, it won't help non-suicide handgun violence. You know that, and I know that, and it's then perplexing why you would think we wouldn't notice.
