I borrowed three books about terrorism. Two of these are from a geographical perspective. I got home and read two papers in one book. These papers were in chapter 7 Building a Safer but Open Society of the book Cutter, Susan L. & Richardson, Douglas B. & Wilbanks, Thomas J. eds. The Geographical Dimensions of Terrorism (New York: Routledge, 2003). The papers were Harlan Onsrud, Openness versus Security of Geographic Information in Cutter, Susan L. & Richardson, Douglas B. & Wilbanks, Thomas J. eds. The Geographical Dimensions of Terrorism (New York: Routledge, 2003) p. 207-212 and William B. Wood, Geosecurity again in Cutter, Susan L. & Richardson, Douglas B. & Wilbanks, Thomas J. eds. The Geographical Dimensions of Terrorism (New York: Routledge, 2003) p. 213-222.
