The analysis highlights the significance of community policing, crisis communication, multicultural interaction, emotional intelligence, and media literacy training. The article concludes that adopting and adapting international best practices can significantly enhance the effectiveness, legitimacy, and public trust toward internal affairs systems in developing countries.
