My point exactly. Whether he intended to hit the friend or Sandy doesn't mitigate the action. The rule that was suspended was that they had to take fire first before returning fire. Definitely wrong. She wasn't watching them shoot her son and dog though. That happened much earlier and some distance from the house in the woods.
He did draw her looking out toward the evil men who had been killing her dog and son. No, she did not see them killed but she was looking towards them when he killed her deliberately.
And I do call them evil, I don't give a dang in whose employ they were in.
