One significant drawback of criminal profiling is the wide variation of results among profilers. Factors that affect this variation includes the difference in investigative background among profilers, which necessarily influences the profiling being done. The prove inconsistency among profiler results demonstrates a basic lack of validity (Young, 2006, p. 22).
Godwin (2002, p. 8) also notes that profiling serial murders generally lack a rigorous examination of existing data and contributing factors beyond case reports. In other words, the type and amount of data are insufficient to truly create an accurate profile of a serial murderer in any more than accidental terms.
Despite these drawbacks, there are also significant advantages to the criminal profiling process, one of which is the identification of signature behavior (Young, 2006). Such a typology can help investigators link apparently unrelated crimes by increasing the depth of the investigation. In turn, this will also result in greater ability among investigators to identify and arrest criminals.
In conclusion, it is clear, as Young (2006) points out, that there is much room for improvement in...
Areas of consistency, especially should be addressed in terms of individual profiler variations, inconsistencies in the data, and inconsistencies in the investigation process.
Still, it is equally clear that criminal profiling adds a dimension to police work without which law enforcement would have been less effective. Indeed, although some profiles prove to be highly inaccurate, others have helped investigators make great strides in identifying and incarcerating dangerous criminals.

Criminal Profiling as an Aid for Apprehending Serial Killers Popular media loves to emphasize the role of the criminal profiler in apprehending serial killers. It has been a central them in books, television shows, and movies for the past two decades, and the concept of the feisty criminal profiler interviewing wily and brilliant convicted serial killers in an effort to gain insight into active serial killers has become so iconic that
Criminal personality profiling has emerged as an important forensic science tool because of the growing need for professionals in the behavioral science sector to help law enforcement personnel in dealing with various crime scenes. The paper discusses this technique in light of its definition and recent advances as a science rather than an art. The discussion demonstrates how various attributes of a crime scene and investigations have led to its
Criminal Psycholinguistics as a Predictor and/or Indicator of Criminality (rewritten for grammar) Language is used differently. Humans use it in many forms and in many means. As it represents someone's character, language helps everyone to perceive what kind of profile a person has. Thus, this brought the researcher to explore the psycholinguistics of criminals. In this thesis, the researcher will focus mainly on the collective study in determining a criminal based on
Brown, in her biographic article for World of Forensic Science, states, She views investigative criminal profiling as a dynamic process that does not conclude until a suspect is arrested and convicted. She deems it a support process for the criminal investigative team, made up of a combination of four skills: investigation, forensic analysis, psychological assessment, and the application of cultural anthropology. Brown considers this type of profiling to be a

The process is perfectly logical and obviously makes infinitely more sense than continuing to search for individuals who bear no resemblance to the descriptions provided by reliable sources. However, the same legitimate techniques with respect to specific evidence of crimes also
