Criminal Justice also refers to enforcement of crime and the outcome.
Issues here are how we treat victims of crime differently from criminals, whilst this is not the case generally. Often a victimised child may grow up to commit offences themselves.
Another issue is sexual assualt. We see sexual assualt as being something committed by a stranger, yet many assaults are committed by people the victim knows.
White collar crime is another problem. The term was coined by Edwin Sutherland when he said that although lower classes commit street crimes, the higher classes are able to commit crimes as well and furthermore get away with it. You could explore how the Australian Securities and Investments Commission take action, and compare it with the police, a good point to start with is John Braithewaite's model that ASIC will start off enforcement by (in order):
-Ignoring complaint;
-Educating Complaintant on how to avoid this in the future;
-Notifying the Company;
-Notifying the public of practices;
-Administrative Penalty;
-Revke license/prosecution.
Remember that Governemnts don't want to intervene in the private sector, and need to keep a balance, anything the Government do to a company, can destroy investor confidence in that company leading to a collapse.
