Types of Criminal Profiling
According to Bartol & Bartol (2017), there are five broad categories of criminal profiling, but they are not mutually exclusive and are frequently used in tandem with one another to aid investigations. The first type of criminal profiling covered in the text is commonly referred to as psychological profiling: the profiling of known individuals like suspects. The goal of psychological profiling is risk or threat assessment: to determine how serious a person may be if they have threatened violence. Similarly, psychological profiling can be used on persons who have been flagged for violating social norms or who have acted out. As helpful as psychological profiling can be to investigators, it is important to note that the process can be misleading and even harmful to investigations (Sample, 2010). Psychological profiling methods are not necessarily grounded in research, and can lead to spurious results and prejudicial data.
The second type of profiling Bartol & Bartol (2017) cover is suspect-based. Also known as prospective profiling, suspect-based profiling uses acutorial methods and statistics to help narrow down a list of potential features or characteristics that would help investigators identify potential threats. Unfortunately, suspect-based profiling frequently involves racial profiling. As Kocsis & Palermo (2013) point out, trait-based profiling can be problematic because this method of profiling raises serious ethical and legal concerns.
Third, geographical profiling helps law enforcement officers to narrow their investigation to a specific location. It is data based and actuarial, often using complex analyses of multiple data points in order to show where a suspect or perpetrator might be hiding or planning their next...…of death.
No one type of profiling is necessarily more promising than any other. Each should be used in accordance with the details of the crime and the nature of the investigation. However, crime scene profiling provides a comprehensive method that takes into account multiple variables.
Crime Scene Profiling
Crime scene profiling is neither fully reliable nor entirely valid because it is not based on raw data; instead it relies on subjective impressions and potentially biased observations (Bartol & Bartol, 2017). To mitigate problems associated with crime scene profiling, it may be helpful to use a team of investigators with diverse perspectives and backgrounds. Similarly, crime scene profiling should ideally be combined with other methods of profiling to provide investigators with a more robust and valid data set that reduces the likelihood of false positives.…
For example, Cook County, IL, has built a network of support for juvenile female offenders within the local community. The county has developed its own gender-specific assessment and treatment guidelines and has trained youth-facing community workers on assessing juvenile offenders and recommending programming. (Juvenile Justice Journal, 1999, p. 30). Also, the county designed a pilot network of social service agencies in order to provide a community-based continuum of care. (Juvenile
Criminal justice system refers to either the state or federal set of agencies and processes which are created by governments to control crime and to engage in penalties and discipline on those who break the law and who hurt others or damage property. "There is no single criminal justice system in the United States but rather many similar, individual systems. How the criminal justice system works in each area depends

In some areas, and especially in low-income housing projects, crime has actually increased. Another problem that Powell addresses in
The reduction occurs through allowing the counties to acquire other methods of jailing apart from the prisons. This includes out-of custody rehabilitative treatments, which could serve in reducing the number of the criminals taken to the prisons. However, the AB109 criminals must be individuals whose crime are not violent and not that serious as provided by the law. This means that that jailing of the A109 criminals in other
