I disagree.

This is a controversy among the States, therefore it is a case or Original Jurisdiction for SCOTUS. Accordingly they can have a full trial, with expert testimony, witnesses, exhibits, even DISCOVERY if they so choose.

It's rare, and hasn't happened in over a century, but they certainly can allow evidentiary proceedings in this instance.

This.

5-10 miles in any direction and they are surrounded by guys dialing in hunting rifles

Lancaster COUNTY is red.

Lancaster CITY is blue.

The city is blue, but the county is red.

Seriously, Charlie shot a guy when they tried to rob the Pharmacy

They can, and do, have AR's.

Lots of other guns too, mostly for hunting.

This is just totally false.

Lancaster city is blue, but the rest of the county is Red.

Bingo.

The city is a dot of blue in a sea of red.

Age.

In my county over 75% of the deaths are octogenarians or older.

This overwhelmingly hits the elderly, take a look at the demographics.
