WARNING

When a life is imperiled or a dire situation is at hand, safe alternatives may not exist. To deal with the worst-case scenarios presented in this book, we highly recommend—insist, actually—that the best course of action is to consult a professionally trained expert. DO NOT ATTEMPT TO UNDERTAKE ANY OF THE ACTIVITIES DESCRIBED IN THIS BOOK YOURSELF. But because highly trained professionals may not always be available when the safety of individuals is at risk, we have asked experts on various subjects to describe the techniques they might employ in those emergency situations. THE PUBLISHER, AUTHORS, AND EXPERTS DISCLAIM ANY LIABILITY from any injury that may result from the use, proper or improper, of the information contained in this book. All the information in this book comes directly from experts in the situation at hand, but we do not guarantee that the information contained herein is complete, safe, or accurate, nor should it be considered a substitute for your good judgment and common sense. And finally, nothing in this book should be construed or interpreted to infringe on the rights of other persons or to violate criminal statutes: we urge you to obey all laws and respect all rights, including property rights, of others—even after the apocalypse. —The Authors
