Parts of the police culture may need to evolve in order to establish a more inclusive internal climate. Yet before seeking to influence a culture shift police leaders first need to understand it. This chapter provides an overview of the common descriptions of the police culture, how the culture might have changed over time and how new recruits are socialized. This chapter also highlights the types of cultures that tend to be found within policing as well as the different cultures that might emerge from one police organization to another. Excerpts from interviews with current and former serving police officers are also included to illustrate their experiences as they relate to key points discussed throughout this chapter.
