Quite possibly true... I refuse to look down on somebody because they decline to get involved in a fight. That may not be the way I would react... or it might be - you never REALLY know what you’re going to do in a given situation until you do it.In the past year or so, a LEO was being attacked. He was down on the ground being beaten. IIRC, the perp was either grabbing his gun or had grabbed the gun. A CHL passerby shot the perp. Saved the policeman's life.
But some on here would have looked the other way. "Not a member of my family. Not me being attacked."
Even if you’ve done well under fire in the past, there‘s no way of knowing what you’ll do in the future. I’ve seen men who claimed to be brave (and who had been brave in the past) cowering under fire and others you would have pegged as cowards dashing through shot and shell. So much depends on the situation at the moment.
