"Talking and dealing with armed people involved in critical incidents may be one of the most challenging tasks in Law Enforcement. [Dr. Hammer] took the very interesting step of not only analyzing the mindset of the perpetrator, but of analyzing how the negotiator can work with him or her to affect the outcome. However, more significantly you have armed the negotiator with a roadmap to traverse the delicate terrain ahead. You point out how to identify the "frame of mind" and work within it. It is brilliant, simple yet can be hard to do. Thanks again for your work."
