Shoot him in the head, neck, legs, crotch, arms, anywhere would have stopped him.
If sheeple stampede prevented a clean shot initially said minute of torso target would have presented itself eventually. I like to think my first reaction if alone would to seek cover or concealment.

Shoot’n scoot per se. My SWAG on the what if’s and maybes.
