“… and began dragging an object behind the truck through the parking lot to the field nearby.”
Hey, the perp could have had Covid. You want to avoid touching dead bodies like that. This was a safe way to transport him.
I consider the driver as defending his property.
Nothing more deserved by the perp in this case because had the F-150 owner not shot the perp, the perp could have shot the driver’s legs (and after the F-150 driver fell from the shots to his legs, the perp would have shot his head), forever preventing him from walking. Certainly the perp being under the vehicle his was somewhat protected. I feel no sympathy for the perp.
