Web17 Jul 2024 · Goldstein (1979) offered the problem-oriented approach as a means of improving police outcomes. Specifically, he stated that the police need to ‘develop a more systematic process for examining and addressing the problems that the public expects them to handle’ ( Goldstein, 1979, p. 236).
