"You feel betrayed by your teachers and administrators, these people you trust," said 15-year-old Carolyn Magos. "But then I felt selfish for feeling that way, because, I mean, if it saves one life, it's worth it."

"They were traumatized, but we wanted them to be traumatized," said guidance counselor Lori Tauber, who helped organize the shocking exercise and got dozens of students to participate. "That's how they get the message."

The plan was to tell the truth to the students at an assembly later in the day. But word that it was all a hoax began to spread before the gathering. Tauber said some counselors and administrators revealed the truth to calm some students who had become upset.
