I left out the part of the story where he turns to the woman who was to have been stoned and says "go and sin no more". We must be responsible for our actions and try to do good, but none of us are really very good at that, and will always make mistakes. Because of that, it's also our responsibility to show grace and forgiveness to others. If it's impossible to leave behind foolish or terrible things we've said or done, we're all doomed.
For what it's worth, I didn't really want my original comment to be read as aimed at King or the reporter. I think the reporter (and his editor) was wrong to do what he did and got a taste of his own medicine. It would've been far better had the whole story remained untold.
