Question

evaluate the system crime and punishment

Answer 1

Criminal punishment on moral grounds while at the same time having a criminal justice system that resonates with the very people to protect and serve whom it was created.

A second question concerns the necessary conditions for criminal liability and punishment in particular cases. A third relates to the form and severity of punishment that is appropriate for particular offenses and offenders. Debates about punishment are important in their own right, but they also raise more general problems about the proper standards for evaluating social practices.

The main part of this theoretical overview of the subject of legal punishment concentrates on these issues of justification. That discussion is preceded by an analysis of the concept of punishment and is followed by a brief account of how theories for justifying punishment can relate to decisions about the substantive criminal law and criminal procedures.
