It’s illustrative to consider what a “shelter-in-place” might look like in two different cites, let’s say Boston and DFW.
To the perps, Boston would look like a lot of potential hideouts because very few people are armed. DFW would look like like a bunch of potential booby-traps with a shotgun blast waiting behind every door.
I’m in a small town in northern California and I would guess he would have a 90% chance of an armed welcome here also.
