I was taught from an early age that if you point a weapon at anything, pull the trigger. Just common sense as to why you pointed in the first place.Neil and Kim at Geauga Firearms Academy put out some very educational/informative videos. This one Neil talks about as a licensed carrier, when you should engage a target and can you deal with the aftermath. It makes one think and we all know that there is a very short window for that when using deadly force.
Hope you enjoy the video, and no, I have no connection with them whatsoever.
