Severide: We need to figure out who’s pulling these alarms. Headmaster: Of course, yes, my staff and I will figure out who’s behind this. Casey: We’d like to talk to them. He needs to understand he’s putting people’s lives in danger. Headmaster: I’m afraid that’s not possible, but we’ll make sure they get the message. Severide: What do you mean that’s not possible? Headmaster: Well, our students are entitled to their privacy, lieutenant, and disciplinary matters are kept in strict confidence. Casey: What? Headmaster: I have to insist on it. The families of Stover Academy would expect nothing less. Severide: You mean these private school parents expect you to shield their kids from prosecution? Headmaster: Hold on. We’re talking about a prank here – a sophomoric and irresponsible one to be sure. Severide: Pulling a false alarm is a crime. Casey: OK, Kelly. Headmaster: If you can’t have a calm, rational discussion, I’m afraid I need to ask you to leave the premises. Severide: We’re going to find out who did this, with or without him.
