Tier A - Overview
Date: December 19, 2016
Location: Berlin (Germany)
Summary: Berlin truck attack is remembered as a bombing that leveraged planning, access, and timing to produce mass harm. The prevention lesson is not only about devices, but about the observable preparation pathway that can precede a detonation.
Key prevention lens:
- Escalating grievance or fixation tied to a person, place, ideology, or perceived injustice.
- Leakage: statements of intent, threats, or ominous communications that merit documentation and follow-up.
- Preparation behaviors: access-seeking, planning, acquisition, testing, rehearsal, or sudden "energy burst".
- Review how predictable routines, access points, and unattended-space vulnerabilities can be exploited.
