The UAPD and the Critical Response Team staged the training scenario, reenacting the scene over several hours for different groups of officers, using volunteer actors for victims, gunmen and hostages. The drill was to test not only the officers, but support staff and the U of A's administration as well, preparing the school to face violent situations.
