In my experience, having lived in a few different places, calling 911 is the
last thing I want to do when I need something to happen NOW.
You were dealing with the problem, the 911 call would have been back
up & maybe a way to get answers.
Where I lived in Minnesota there was one sheriff for the northern
part of the county, I'd never expect them to show up "now", just eventually.
But he generally knew most everyone and what was going on in the area.
