The "the first rock thrown again" line also refers to the bible. Somewhere in there is a scene where someone is being stoned to death. And then jesus - i think it was him, but im not sure, might even be him who is being stoned - says "the one who is without sin throw the first rock" and no one moves... perhaps this isnt exactly the story, but the situation. :) So i think in this song it means a mistake which is made again, like some of you already said.
