About 30 students who showed up to attend their prom this past weekend were not allowed to enter. They did not bring their student ID badges with them. Those ID's are required at all school sponsored events. An assistant principal at Caddo Magnet High School says this is the policy and the students know it. The purpose of the policy is to make sure all of the students attending school events are safe. But some parents says this ruined what should have been a special prom night for several teenagers.
