More salt-of-the-earth, middle American conservatives in a bowling alley as opposed to say... a Starbucks. A deranged "right wing" shooter, one might think, would target an establishment frequented by more leftists, antifa types. Perhaps?
I’ve seen bowling league members span the political spectrum. This tragedy appears to be a case of mental illness inadequately treated, as opposed to a political jihad.
If you want to kill lots of people in a small town, go to where there are lots of people, i.e. a bowling alley.
