Abstract
This chapter builds upon discussions in the previous ones about leakage of threats and other warning signs prior to mass shootings. The discussion here centers on assessing and managing threats in order to try to prevent mass shootings from occurring. The argument will be put forward that threat assessment allows for the seriousness of threats to be ascertained. This approach is two-fold in nature involving the assessment of the threat, as well as the individual who made the threat to determine whether they pose a danger to themselves or others. Moreover, it generally involves a follow-up plan for the threatening individual to be managed. Interviews with experts in this field provide advice relating to the process of carrying out threat assessment and management.
