That is when the woman said her husband shot the man.
Now IANAL, and think that justice was served here, even if it was rough justice. Actually rough justice might be exactly what this sort of situation calls for. But Miguel questions whether this is a deadly force situation. It seems to me (remember IANAL) that the parents escalated the situation that resulted in gunfire. Like Miguel, I hope that no charges will be brought.
But everyone should remember that a CCW permit is not a Justice League membership card.
