To exemplify the state-of-the-art in applying problem-solving techniques to policing domestic violence, the paper uses data, policies and practices of the San Diego, CA, Police Department. The paper reviews the problem-solving paradigm in policing and its relationship to the scientific method. It compares police knowledge and practice to the goals of the paradigm, element by element. It concludes with two major implications of the domestic violence experience: the need for continuing revision in scientific "truth," and the even greater need to improve police measurement and management of the various types of domestic violence. A cultural evolution in policing must develop to support the scientific revolution of the problem-solving paradigm. This cultural evolution can move forward most rapidly by a growing partnership between police and criminologists or other professional scientists, such as the public health community in the case of domestic violence.
