THE FBI AND RELIGION by Sylvester A. Johnson and Steven P. Weitzman (2/7, University of California Press) is another more scholarly work focusing on "faith and national security before and after 9/11." Northwestern University's Johnson and University of Pennsylvania's Weitzman have collected a series of essays such as "Policing Public Morality," "A Vast infiltration," and "Allies against Armageddon?" which explore threats to religious liberty by describing the FBI's relationship over time with a variety of religions and groups, including, Jews, Catholics, Protestants, Mormons, Muslims, and Branch Davidians. Very specialized and extensively researched.
