Towards systematic knowledge building: An anti-crime research and development continuum

This response argues that the National Research Council (NRC) report, while valuable and thorough, would have benefited from conceptualizing evaluation activities along a continuum of knowledge development, with evaluations initially verifying the effectiveness of program concepts, before moving to evaluations of the feasibility and generalizability of anti-crime strategies and, finally, to evaluations of the costs and benefits of implementation of new strategies.
