The alcohol-monitoring bracelet Lindsay Lohan donned after leaving rehab was not a dummy as we all assumed, but was in fact a real functioning SCRAM device. The bracelet reportedly detected alcohol in Lohan's perspiration several hours before her DUI arrest, and according to its programming, alerted her lawyer Blair Berk who then scrambled to locate Lindsay. Too late - Lohan was arrested and booked for DUI and possession before Berk could find her.
So are we all going to apologize to Lindsay for our jokes about her fake alcohol monitor? I didn't think so...
