did he mean to keep shooting and run short of ammo so he retrieved another weapon?

what was the round count in the original weapon?
I'm sorry but I can't find good info, maybe you can link?

do you want a prediction?
NOT GUILTY or charges dropped

short of more info I can only offer my views, like anyone wants that LOL

I say once someone initiates an act of aggression sufficient to warrant deadly force, the game isn't over until someone has died (hello? deadly force?)

all those coward PC concealed carry instructors and others who
"shoot to end the fight" are full of crap and are responsible for this

you shoot to kill
if you don't want to kill them then you have no business using a firearm
they are the machinery of death plain and simple
