Nor a Criminal Profiler an Expert Witness.

The article by Kocsis and Palermo, published in 2016, examined the findings of research which had assessed the validity of the investigative technique colloquially known as . These findings were subsequently considered within the framework of their relevance to the admissibility of the technique as a form of expert witness evidence. The overall conclusion was that a discrete facet of the profiling technique may satisfy some of the requisite legal criteria for admissibility in jurisdictions within the United States.

Criminal profiling as expert witness evidence: The implications of the profiler validity research.

The use and development of the investigative tool colloquially known as criminal profiling has steadily increased over the past five decades throughout the world. Coupled with this growth has been a diversification in the suggested range of applications for this technique. Possibly the most notable of these has been the attempted transition of the technique from a tool intended to assist police investigations into a form of expert witness evidence admissible in legal proceedings.

Disentangling criminal profiling: accuracy, homology, and the myth of trait-based profiling.

The scholarly literature over the past decade has chronicled a growing problem in the forensic technique colloquially called criminal profiling. The basis of this conundrum appears to originate from a concept referred to as "offender homology," which presumes an inherent uniformity among offenders that is believed to underpin the analytic process incumbent to criminal profiling. Studies thus far conducted have apparently struggled to find evidence of offender homology, and based upon these findings arguments have been promulgated that various approaches to criminal profiling imputably labeled as "trait-based" are therefore not viable.

The structure of the US legal system, which relies on the presence of different courts to provide for the impartial administration of justice, both civil and criminal is discussed. Therefore, all the steps to conviction or acquittal of the American criminal trial, are taken into consideration. However, there is the presumption of innocence of the accused and the prosecution must prove his guilt beyond any reasonable doubt.
