There are so many good discussions and advice on this thread. Cssutton, thank you for your posts. Very informative, and obviously from someone who have thought very carefully of the topic. It does remind me of a story I’m still thinking of even today.
The story was told by an instructor at my concealed carry permit class. A man, a good man by all accounts, was driving by a warehouse at night, next to some housing unit at some rough neighborhood, on the way home. While he drove by he saw a man on top of a woman, a knife in his hand, stabbing the woman repeatedly, mercilessly. The driver stopped, hopped out of his car, screamed at the aggressor to stop, or he would shoot. The aggressor ignored him, continued stabbing at the woman, presumably with an intent to kill, so the driver discharged his firearm, and killed the man.
The good Samantha was arrested, and in the court, found out that the woman was the aggressor’s wife, and she had stabbed him just before the incident. So the husband seriously injured, grabbed the knife, attacked his wife, and since he was seriously injured, in a delusional state, he didn’t hear the warning from the shooter. Since the good Samantha fired his gun while his own life was not in danger, he was pronounced guilty, charged, and sent to jail.
The story was to warn gun owners that they are not law enforcement. OP, this might also have an impact on your neighbor, if circumstance calls for him to discharge his gun, and he kills your intruder for you.
Here is the moral dilemma. If you pass by a scene and witness someone stabbing another to death, can you live with conscience to just “let it go” even if that is legally the safest way for yourself? Calling 911 is moot point. By the time the police arrives, you can be 110% certain that the woman would be dead. If the story didn’t have such a twist, and the aggressor really is an aggressor instead of a victim, would the jury have more sympathy toward the shooter?
