ABSTRACT
This paper investigates the use of the National Incident Management System (NIMS)'s Incident Command System (ICS) in law enforcement since Homeland Security Presidential Directive 5 was issued in 2003. It attempts to answer the following questions: (a) To what degree has law enforcement adopted the NIMS style ICS?; (b) To what degree has the NIMS/ICS framework been applicable to law enforcement?; and (c) Is the NIMS style ICS effective in the law enforcement response environment? The research includes a review of relevant case studies and literature and also includes the analysis of a survey instrument sent to 1,220 current and former law enforcement practitioners across the United States. The survey includes both open- and closed-ended questions. The data from closed-ended questions were compiled and displayed. Data from open-ended questions were grouped thematically. Responses were then assessed and compared with information gleaned from the literature review. Results indicate the system has been widely adopted by law enforcement, and its use is applicable and effective in some law enforcement responses. Its use in the highly chaotic initial phase of incidents, however, remains an open question.
