Another What if....again!
I know certain elements of this scenario have been discussed and I apologize in advance if in my research I missed a thread that did specifically deal with this.
To my wife's disagreement in more than one debate, I have always been of the belief that if a BG points a gun at you, that they intend to use it. In which case I will certainly use mine (if no escape options exist). Contrary to her belief that "alot of times they will let you go" and just want your $ or your car, I am not willing to put the decision of my life into someone else's hands. To her scenario of "What if it's a fake gun or some 19 year old playing around?" I respond that if I have what appears to be a real weapon pointed at me, even if by some idiot 19 year old driving by in a car, then I would probably spend my days in court defending my actions to a judge and his mother explaining that her little baby did something very stupid in today's day and age and it cost him.
Now, with that, a scenario. I am in a a gas station in in the gum and candy aisle when a BG walks up to the clerk with what appears to clearly be a gun and points it at him. He barks and threatens the clerk and doesn't see me. Through the conversation I ascertain that it is imminent that the clerk is about to get shot for not cooperating properly. There is no threat at anytime to my own life or well being, only to the clerk and I am the only other person on earth right now that could save the clerks life with my actions.
Questions: Aside from the moral obligation, do I have a legal right to fire on the BG before he fires upon the clerk?
What are the legal ramifications that I could face if I decided to do so?
Are those ramifications different if I fired upon him AFTER he fired upon the clerk?
Thanks for your thoughts!
