Security and crime are often in close proximity but not always studied together. This month's episode features Martin Gill a criminologist who made the study of crime and security his life's work.  After a decade as a lecturing professor at the University of Leichester,  Mr. Gill started Perpetuity Research in 2002 and continues to provide very high quality research, both qualitiative and quantitiative,  on what works -- and more importantly what does not --  on many different areas of the security field.    In addition to leading the annual Security Research Initiative reports, Martin Gill is also the a contributing author and  editor of many criminology and security textbooks including  "The Handbook of Security" -- now in it's third edition.
