I disagree. I'm not sure where you receive your LEO training, but I know you were not trained to shoot someone with the intent to maim, or kill. There are no CCW classes that train someone to shoot to maim, or to kill either.
You use your firearm to stop the threat. That's it, and that's all. The threat you perceive ultimately dictates how many rounds are fired. How you articulate the incident afterward to those asking the questions ultimately determines whether you get to go home, or to jail.
At least that's how it is here in the good 'ol Commonwealth of Kentucky.
Ya'll have a good night
