Girls at California's Linden High School grew upset at the repeated thefts from their lockers during gym class. So one of them, Justine Betti, decided to hide in one of the lockers and catch the thief in action. She managed to record on video one of the teachers going through the girls' bags and apparently taking something out of one of them. When she went to the principal with the video, he told her he'd investigate it but said she should erase the video. Fortunately, she'd already sent a copy to her dad. The teacher is now on administrative leave while the school investigates the thefts.
