In all of these staged events, whether the theme is UFOs, accidents, murder victims or shooters, the elements are the same:
- Students are not informed drills are drills or fake events
- Parents are not notified before hand
- Often, not all school staff are aware of fake scene
- Local police participate, acting out roles of investigating officers, taking witness reports, etc.
- All these staged incidents have to do with the unexpected, and the violent
- Justification given by educators is that these drills (paraphrasing) "foster critical thinking skills," "encourage creativity" and so on
