Mosaic threat assessment method

Mosaic is a threat assessment method developed by Gavin de Becker, author of The Gift of Fear. The book is about security strategies for dealing with stalkers, assassins, and other forms of civil violence.[1][2]

Notes

  1. Gavin de Becker is widely regarded as our nation's leading expert on the prediction and management of violence. [1]
  2. He developed Mosaic — a threat assessment tool used by the Supreme Court as well as police departments and schools across the country — to predict whether someone will turn violent. [2]


  • Rarely were incidents of school violence sudden, impulsive acts. Attackers do not “just snap,” but progress from forming an idea, to planning an attack, to gathering weapons. This process can happen quickly, but sometimes the planning or gathering weapons are discoverable. [3]
