BANGKOK - With her mouth taped and hands tied behind her back, 15-year-old Benjamaporn Nivas sits under a skytrain station looking stonily past the shoppers in Bangkok's Siam Square district.
She's wearing her school uniform. There is a pair of scissors on her lap, along with a sign that says: "This student has broken rules by having hair longer than her ear lobes and bangs that cover her face. This tarnishes the image of Thai students. Please punish her."
