The appearance of Oscar Newmans Defensible Space in 1972 signaled the establishment of a new criminological subdiscipline that has come to be called by many Crime Prevention Through Environmental Design or CPTED. Over the years, Mr. Newmans ideas have proven to have significant merit in helping the Nations citizens reclaim their urban neighborhoods. This casebook will assist public & private organizations with the implementation of Defensible Space theory. This monograph draws directly from Mr. Newmans experience as consulting architect.
