Book excerpt: Mass shootings have become more prevalent in the past few decades, especially within the United States. Whilst the United States has suffered from hundreds of mass shootings over the years, policy change relating to guns has been limited in scope, particularly when compared with other developed nations. Recognizing that the United States has a different history and culture, new policies must be undertaken to mitigate the occurrences of mass shootings with the understanding that its response should not be the same as other developed nations. Examining Gun Regulations, Warning Behaviors, and Policies to Prevent Mass Shootings is a critical reference book that analyzes the debates around and responses to mass shootings with a two-fold focus: the prevention, preparation, response, and recovery of mass shootings and gun proposals raised following these incidents. With a specific look at the 2017 Las Vegas shooting, the author scrutinizes the news media coverage following the incident to document its role in policy discussions, while also examining new policy responses and gun violence prevention actions that have gained traction since the event. Including the voices of those involved in gun violence prevention, as well as interviews with experts in areas dealing with prevention, preparation, and emergency response and recovery, this book centers on forthcoming themes such as licensing systems of firearms, smart gun technologies, assault weapons and weapons bans, and the portrayal of mass shootings in media. This book is essential for policymakers/lawmakers, news media, politicians and government officials, emergency management personnel, academicians, researchers, and students.
