When in an armed conflict you never shoot to disable.You shoot to terminate the other party. If you pull that thing out, intend on killing what you shoot. That advise works for civilians and police. The reasons or lack of reason for the shooting will be reviewed in the court system for years.
“You shoot to terminate the other party.”
I don’t mean to be contentious, but it was never my understanding that the usual police procedure was “shoot to kill”.
