The book provides a cross-country study of regulations determining the oversight of all types of internal security forces and a set of recommendations which aimed at aligning Turkey with EU standards. How to compare the governance of internal security sector across nations? Based on national reviews, systematic tables are elaborated in order to compare different countries on a number of variables relating to civilian oversight of internal security forces. Constitutional, parliamentary, judicial, hierarchical, different internal or external and oversight mechanisms of the three selected EU member states are compared to the situation in Turkey. Additionally, citizen and local authorities' involvement in security policies and issues is the subject of discussion as this constitutes an important element of civilian oversight of internal security forces. For each dimension of oversight, variables are elaborated and used for measuring the nature and quality of oversight of police forces (including gendarmeries).
