# What Are the Risks of Terrorism? **URL:** **By** John Mueller, Mark G. Stewart, Trevor Burrus, Aaron Ross Powell **Published:** December 11, 2015 --- John Mueller and Mark G. Stewart join us to discuss their new book, Chasing Ghosts: The Policing of Terrorism (2015). How did the effort to foil American terror plots change after 9/11? How are terrorists deterred from their goals? John Mueller and Mark G. Stewart join us this week to talk about why our government needs to think realistically about combating terrorism. **Show Notes and Further Reading** Mueller and Stewart's new book on how our post-9/11 government ends up chasing incredible terrorist threats, [_Chasing Ghosts: The Policing of Terrorism_](http://www.amazon.com/Chasing-Ghosts-The-Policing-Terrorism/dp/0190237317) (2015). Mueller mentions a 2010 comedy movie about British jihadists, [Four Lions](http://www.fourlionsthemovie.com/). Mueller also mentions a book of student papers that he edits that follows post-9/11 terror cases in America, [_Terrorism Since 9/11: The American Cases_](http://www.amazon.com/Terrorism-Since-11-American-Cases/dp/1934849731/) (2015). Garrett Graff's [_The Threat Matrix: The FBI at War_](http://www.amazon.com/Threat-Matrix-FBI-War/dp/0316068608/) (2012) is a good overview of how the FBI currently responds to terror threats.
