Okay, let's say it is that situation just be mere happenstance.
Mild-mannered John Smith is chilling in his bedroom watching TV with his wife Jane Smith when suddenly, (alpacca out of loving nowhere) five thugs bust through the windows in the other room.
The lights are off, so the criminals are unaware of the presence of the couple.
Immediately, Johnathan mutes the television and reaches for his Colt .45 from his sock drawer!
Silently of course.
He then cracks the door open to evaluate the situation, his mind racing, his adrenaline pumping!
John has the element of surprise on his side. Thinking quickly and humanely, he swiftly opens the door, gets behind his sofa and rapidly pulls the trigger aiming at each criminal's hands.
He probably missed by a hair and hit some of them in their pelvic region or their stomachs. Who knows?
We can't predict these things. The only way to get an accurate reading is to have it happen in a controlled environment.
