Policing in the 21st century is becoming increasingly complicated as economic, political, social, and legal circumstances continue to compel police organizations to evolve. To illustrate the complexity of policing in the 21st century and cover themes common to police organizations around the world, Exploring Contemporary Police Challenges: A Global Perspective is organized into six sections, which cover the key policing challenges across the globe. Based on US President Barack Obama’s 2015 Task Force’s organization into six broad pillars, this volume contains contributions from policing experts focusing on Building Trust and Legitimacy; Providing Policy and Oversight; Utilizing Technology and Social Media; Developing Community Policing and Crime Reduction; Providing Police Training and Education; and Facilitating Officer Wellness and Safety. Scholarly analyses and discussions of these issues in 16 countries on 6 continents offer a global perspective on policing in the 21st century. This volume simultaneously enhances the scope of policing scholarship and demonstrates that no country can sidestep the need to adjust to these rapid and profound changes.
