CRIMINAL PROFILING Principles and Practice

Offender profiling , also known as criminal profiling , is an investigative strategy used by law enforcement agencies to identify likely suspects and has been used by investigators to link cases that may have been committed by the same perpetrator.

In the s, most researchers believed offender profiling was relevant only to sex crimes , like serial rape or sexual homicide , but since the late s research has been published to support its application to arson , and then later terrorism and burglary Psychological profiling is described as a method of suspect identification which seeks to identify a person's mental, emotional, and personality characteristics based on things done or left at the crime scene.

There are two major assumptions made when it comes to offender profiling: behavioral consistency and homology. Behavior consistency is the idea that an offender's crimes will tend to be similar to one another. Homology is the idea that similar crimes are committed by similar offenders. Fundamental assumptions that offender profiling relies upon, such as the homology assumption, have been proven outdated by advances in psychology and behavioral science.

Profilers have been noted to be very reluctant to participate in studies of profiling's accuracy. There is a lack of scientific research or evidence to support psychological profiling as useful in criminal investigations. Critics question the reliability, validity, and utility of criminal profiles generally provided in police investigations.

Even over the years common criminal profiling methods have changed and been looked down upon due to weak definitions that differentiate the criminal's behaviors, assumptions and their psychodynamic process of the offender actions and characteristics that occur.

In other words, this leads us to poor and misleading profiles on offenders because they are based on opinions and decisions made up from one profiler conducting research on the offender. The more recent attempts at research into profiling's effectiveness have prompted researchers to label it as pseudoscientific. The profession of criminal profiling is highly unregulated. Officers were able to find truth in whichever profile they viewed, believing it accurately described the perpetrator, demonstrating the presence of the Barnum effect.

The most routinely used typology in profiling is categorizing crime scenes, and by extension offender's personalities, as either "organized" or " disorganized ". A typology of serial sexual homicides advocated by Robert Keppel and Richard Walter categorizes them as either power—assertive, power—reassurance, anger—retaliatory, or anger—excitation.

Criminal profiling can also be ex-ante or ex-post. Descriptive profiling of a perpetrator is a type of ex-post profiling, and can be used to prevent a serial killer from striking again. There are three leading approaches in the area of offender profiling: the criminal investigative approach, the clinical practitioner approach, and the scientific statistical approach.

The BAU "assists law enforcement agencies by their review and assessment of a criminal act, by interpreting the offender's behavior during the crime and the interactions between the offender and the victim during the commission of the crime and as expressed in the crime scene. One practitioner, Turco, believed that all violent crimes were a result of the mother-child struggle where female victims represent the offender's mother. This is also recognized as the psychodynamic approach.

Another practitioner, Copson, outlined some principles for profiling which include being custom made, interactive and reflexive. By following these principles, the profile should include advice that is unique and not from a stereotype, should be easy to understand for all levels of intelligence, and all elements in the profile should influence one another. According to this approach, elements of the profile are developed by comparing the results of the analysis to those of previously caught offenders.

Wilson, Lincon and Kocsis list three main paradigms of profiling: diagnostic evaluation, crime scene analysis, and investigative psychology. Five steps in profiling include: One- Analyzing the criminal act and comparing it to similar crimes in the past. Two- An in-depth analysis of the actual crime scene, Three- Considering the victim's background and activities for possible motives and connections, Four- Considering other possible motives.

Five- Developing a description of the possible offender that can be compared with previous cases. One type of criminal profiling is referred to as linkage analysis. Gerard N. Labuschagne defines linkage analysis as "a form of behavioral analysis that is used to determine the possibility of a series of crimes as having been committed by one offender. An offender's modus operandi is the habits or tendencies during the killing of the victim.

An offender's signature is the unique similarities in each of the kills. Mainly, linkage analysis is used when physical evidence, such as DNA , cannot be collected.

Labuschagne states that in gathering and incorporating these aspects of the offender's crime pattern, investigators must engage in five assessment procedures: One- Obtaining data from multiple sources.

Two- Reviewing the data and identifying significant features of each crime across the series. Three- Classifying the significant features as either modus operandi or ritualistic. Four- Comparing the combination of modus operandi and ritual or fantasy-based features across the series to determine if a signature exists.

Five- Compiling a written report highlighting the findings. There are six stages to developing a criminal profile: profiling inputs, decision process models, crime assessment, criminal profiling, investigation, and apprehension. The first offender profile was assembled by detectives of the Metropolitan Police on the personality of Jack the Ripper , [28] a serial killer who had murdered a series of prostitutes in the s. Police surgeon Thomas Bond was asked to give his opinion on the extent of the murderer's surgical skill and knowledge.

Bond also tried to reconstruct the murder and interpret the behavior pattern of the offender. The characters of the mutilations indicate that the man may be in a condition sexually, that may be called Satyriasis. In , a psychologist in Lackawanna, New York delivered a lecture in which he analyzed the unknown murderer of a local boy named Joey Joseph, dubbed " The Postcard Killer " in the press. In , Dr. Dudley Schoenfeld gave the authorities his predictions about the personality of the kidnapper of the Lindbergh baby.

In , Walter C. Langer developed a profile of Adolf Hitler that hypothesized the Nazi dictator's response to various scenarios, [33] including losing the war. The media dubbed him "The Sherlock Holmes of the Couch. In , after the death of J. They went on to develop the four subtypes of violent crime and the Hunter Integrated Telemetry System HITS database which compiled characteristics of violent crime for research.

David Canter profiled the Railway Rapist. The Crime Classification Manual was published in , and introduced the term "criminal investigative analysis. Profiling as an investigative tool has a high level of acceptance among both the general public and police.

By , FBI profilers were requested in investigations in a single year. By , 12 FBI profilers were applying profiling to approximately 1, cases per year. In the United Kingdom, 29 profilers provided instances of profiling advice between and , its usage increasing steadily over that period.

Surveys of police officers in the United States, the United Kingdom, and Canada have found an overwhelming majority consider profiling to be useful. Profiling's continued popularity has been speculatively attributed to broad use of anecdotes and testimonials, a focus on correct predictions over the number of incorrect ones, ambiguous profiles benefiting from the Barnum effect, and the popular appeal of the fantasy of a sleuth with deductive powers like Hercule Poirot and Sherlock Holmes.

Notable profilers include Roy Hazelwood, who profiled sexual predators; Ernst Gennat , a German criminologist, who developed an early profiling scheme for the police of Berlin; Walter Charles Langer , who predicted Hitler's behavior and eventual suicide; Howard Teten , who worked on the case of Martin Luther King Jr. Douglas , who worked on a wave of child murders in Atlanta in the s. In a review of the literature by Eastwood et al.

A study also showed that profilers were not significantly better at creating a profile than any other participating groups. A study which asked two different groups of police to rate how accurately a profile matched a description of the apprehended offender, with one group given a description of a completely fabricated offender instead of the real one, found that the profile was rated equally accurate in both cases.

There is a lack of clear, quantifiable evidence of a link between crime scene actions A and offender characteristics C , a necessary supposition of the A to C paradigm proposed by Canter Thus, until such inferential processes can be reliably verified, such claims should be treated with great caution in investigations and should be entirely excluded from consideration in court.
