What would you do if you saw someone being beaten in public? English celebrity chef Nigella Lawson became the latest high-profile domestic-abuse victim when her husband, Charles Saatchi, was spotted strangling her at a London restaurant. Experts advise that if you see something awry, you should say something to authorities—or at the very least, make a noise to cause a distraction. If you can, take a photo (which is what happened with Saatchi). Experts say to avoid getting in the middle of an argument, because it could be dangerous for the abused or even you. Most important, call 911 as soon as possible.
