Hi! Under the new syllabus, you don't actually have to refer to specific criteria, as long as you justify your position on effectiveness or ineffectiveness with logical reasoning/cases/media/legislation. That being said, if you wanted to look at 3 criteria that relate to the investigation process, here are a couple of ideas:
-Resource efficiency - Since police only have a certain number of resources, not all cases may be adequately investigated and handled. This may relate to the Use of Technology section, particularly in relation to DNA evidence, which is very complex and can often lead to errors in identification of suspects. There are many well known cases in this area, and you could refer to some choice pieces of legislation such as the Crimes (Appeal and Review) Amendment (DNA Review Panel) Act 2006, which established a board to investigate cases where DNA evidence had been wrongfully handled. However, it has only processed a very limited number of cases, leading to issues of resource efficiency in relation to achieving justice for wrongfully convicted individuals
-Responsiveness of the legal system - You could consider the lack of responsiveness in some areas, such as with the bail laws (see the topic of Bail and Remand) as they apply to young offenders under the 2007 amendments to the Bail Act. It was only in 2011 that any talk of reform began, but prior to this, as all individuals were only allowed one attempt at applying for bail under the amendments, young offenders were particularly negatively impacted, leading to an increase in juveniles held on remand. You would need some articles and statistics to flesh this out a bit more, but the recent reviews by the NSW Law Reform Commission (late 2012) would show increased responsiveness of the legal system to the issue of bail and remand for young offenders.
-Protection of individual rights - The increased search and seizure powers that police now have under the Law Enforcement (Powers and Responsibilities) Act (2002) have definitely lead to the potential for individual civil rights to be violated. For example, sniffer dog searches without a warrant only yield results about 1/3 of the time, but questions about protecting individual rights from abuses of police power remain.
Hope this helps, and good luck!
