Countries in Central and Eastern Europe must cooperate, not only among themselves, but with the European Union (EU) countries as well. Cooperation means not only working cases together, but it also means cooperation in training, education, and research. Increased cooperation, new forms of crime, changes in society, and the changed role of police have created new tasks for police; this necessarily involves changes in training regimens. Training must focus on new approaches to policing; information technology; international cooperation; interagency cooperation; communication, problem-solving, conflict resolution, and negotiation; team-building; use of discretion; stress management; and police ethics. Also, the ever increasing complexity of policing requires higher educational levels for both police officers and police managers. The last pillar of policing is research. Cooperation, training, and education all need research to support them. There is a particular need for more joint research projects among "outsiders" and "insiders" to establish cooperation in this area.
