you can't unring a bell
proverb You can't rescind information that has been shared publicly, especially when it is damaging to a person or organization's reputation. Attempting to do so is usually as futile as "unringing" a bell. How confident are you in this information? Because once we announce it, there's no changing it—you can't unring a bell. You can't unring a bell, even with the best lawyers. So I doubt this scandal is going away anytime soon.
