She was obviously batshit crazy.
These are the kind of people who don't have social skills developed well enough to know that you don't threaten people's lives.
The cops were with her for quite a while. Don't know what might transpire when she tells Buford about the indignities she faced.
Just another in a long line of chances for some crazed hilljack to kill people because the world didn't give them their ignorant desires.
