Technological advances and innovations have been decried by some as a cause of crime and embraced by others as a solution to our crime problem. The author considers new technology in terms of both crime causation and crime convention and control, offering preliminary assessments of the impact--intended and unintended--of each form of new technology, as well as key issues of 1) privacy vs. protection, 2) coercive vs. non-coercive, and 3) public vs. private sector control of justice.
