In this book, we have talked about different types of crime categories: those against people, property, or the public order. We also talked in Chapter 9 about the unique offenses of white-collar crime, cybercrime, and organized crime. In this chapter, we will wrap up the book with a look at massive impact crimes. These are the types of crimes that have many victims who are all connected through tragedy, affecting the community, society, policies, and even laws. This chapter focuses on mass murders and terrorism, as well as the efforts by law enforcement to interrupt these crimes.

This chapter, as in all the chapters in this book, may include triggers for some readers. Please take care of yourself as needed while reading about these massive impact crimes.
