By Jim Giles (Image: Jennifer Grayock/AP) MEMORIAL day weekend 2007 is one that Lindsay Lohan might rather forget. An actor better known for her off-screen antics than her starring roles, Lohan crashed her Mercedes in Santa Monica, California, while over the legal alcohol limit. She checked into rehab. A month-and-a-half later, in July, Lohan emerged and declared that she would clean up her act. Within days she was again caught driving while over the limit. This celebrity story has a twist, however. As part of her efforts to stay sober, Lohan wore an alcohol-monitoring anklet. When photos of her wearing the anklet hit the press, it was the first time many people had heard of such a thing. Yet devices like these are transforming the way alcohol offenders are dealt with in the US. “In the past we’ve said that if you don’t stop drinking and driving, we’ll stop you from driving,” says Bill Mickelson, who has worked with the devices as part of a sobriety programme in South Dakota. “That never got to the heart of the problem. So we’ve developed a way to stop you drinking.” Stopping drink-drivers from driving didn’t always work. Now we have a way to stop them drinking Lohan wore her anklet voluntarily, but most wearers have no choice if they wish to avoid jail. So in the not-too-distant future, could you find yourself wearing such a device if you misbehave after having a few too many?
