Have you ever noticed .....

...that mass shootings are usually directed toward upper-middle-class environments?

It's true!  Most take place at concerts, or in shopping malls, or restaurants, or in swanky clique bars, or suburban schools, or grocery stores, or large outdoor gatherings, or on university/college campuses.

The primary targets seem to be mainly privileged "trophy" type people.

As for the average inner-city or "trailer park" rabble, those types are more likely to end up being victims of local street violence.  Whenever those "lesser" types get shot or stabbed it's usually by another individual or small group from the same neighborhood or general area.
