According to author Frederick J. Lanceley?one of the world's foremost crisis negotiation authorities?negotiators must train and train regularly. For just as the legal field constantly evolves, so does the field of crisis negotiation. The new edition of  On-Scene Guide for Crisis Negotiators reflects this fact. A bestseller in its first edition, this book offers practical advice with regard to the theory, procedures, and techniques of crisis and suicide intervention and hostage negotiation. Two new chapters in the second edition cover negotiation with people under the influence of drugs or alcohol and how first responders can contain a situation until a negotiator can arrive. With a suicide intervention flow chart, a checklist for investigators assisting negotiators, and an on-scene guide for crisis negotiators, this indispensable book provides the tools you need to conduct successful negotiations and "make nothing happen."
