I think there is a lot of sympathy that she was 93 and “she” was a “she”.
Had the deceased been say a 33 year old male, and fired two shots in the ground in front of the officer, most of us would likely be thinking the officer was justified.
Oh yeah, and I think she was black.
You try popping off a few rounds “into the ground “ in front of an officer.
Yer gonna get killed. It aint a game.
