How does this platitude answer the question at hand?
You are one man, not an army, Regardless of your desires, there is little that you can do if you are not in close range.
Popping off a long shot could make you part of the problem if you don’t get lucky.

By questioning who your family is, who you'll protect. You're crouched down behind a barrier, and there's your kid and a stranger, and you bolt with your kid and leave the stranger to die unarmed. Or you're alone, except for the stranger.
What you call a platitude, others call the most profound question in the Bible: "who is my brother"?
“Popping off a long shot could make you part of the problem if you don’t get lucky.”
The operative word is “could”. It all depends on the situation. There have been about 20 recorded where the armed citizen stopped it or at least stopped the killing.
Each situation is different and has to be evaluated. But being former military and former peace officer, I will not simply run away.
The author pushes all the buttons to make his position sound reasonable. He has his family with him.
Well, how about when he does not? No, he is not required by law to get involved. But society has been better when people are willing to risk their lives for other people in trouble.
