As a result, "many of the law enforcement agencies around the world are still quite skeptical of the work of criminal profilers" (Muller, 2000). In fact, in 1994, Curt Bartol polled police psychologists to determine their opinion of profiling; 70% of them questioned the validity and usefulness of profiling (Bartol, 1994)
Douglas was the head of the FBI's Investigative Support Unit for a quarter of a century and developed the modern approach to criminal profiling. Douglas developed his profiling technique by interviewing and studying dozens of serial killers and assassins, including Charles Manson, Sirhan, Richard Speck, John Wayne Gacy, David Berkowitz, and James Earl Ray, then used what he learned from those interviews to develop criminal profiles (Douglas, 2008)

He further highlights the fact that a reliance on profiling can actually harm detection efforts because false profiles can lead the police away from valid suspects and to the identification of people who are not really suspects. In fact, he believes that chance has played a critical role in the apprehension of the serial killers (Jenkins, 1994)
Of the 192 cases, 88 were solved. Of that 88, in only 17% of the cases did a profile help in the identification of a suspect" (Kennedy & Homant, 1997)
There are two practical reasons for this; isolated offenses generally do not present the danger to public safety that would justify the resources required for criminal profiling and serial offenders commit multiple crimes, leading to multiple crime scenes, which assists in the identification of the factors necessary for developing a profile. "Criminal profiling is the process of using available information about a crime and crime scene to compose a psychological portrait of the unknown perpetrator of the crime" (Muller, 2000)
" In 1956, psychiatrist James A. Brussel-also a skilled handwriting analyst-was asked for an analysis to help catch the perpetrator" (Ramsland, 2012)
These forensic mental health professionals rated profiling to be significantly less reliable and valid than those who were given the term criminal investigative analysis for the same process. These findings support the position that profiling is likely to be viewed more favorably if it is referred to by another name" (Torres et al
Unrestricted police profiling would permit law enforcement officers to choose only racial minorities (or individual with any other personal characteristics) as subjects of traffic enforcement. Prior to the modern Civil Rights Era, police officers in many jurisdiction did, in fact, purposely select vehicles occupied by black individuals when conducting traffic stops (Caldero & Crank 2004)
Policing - Criminal Profiling CRIMINAL PROFILING: LEGITIMATE POLICING TOOL or RACISM Due process of law is one of the most fundamental concepts in American constitutional law. The right of citizens to live free from the threat of arbitrary or partial enforcement of law by government authorities was foremost on the minds of the Founding Fathers (Dershowitz 2002), inspired by the Colonial experience under British rule preceding the War of Independence
The right of citizens to live free from the threat of arbitrary or partial enforcement of law by government authorities was foremost on the minds of the Founding Fathers (Dershowitz 2002), inspired by the Colonial experience under British rule preceding the War of Independence. It is expressed in the Fifth Amendment to the Constitution with respect to the federal government and, since 1914, has been applied to the states through the Equal Protection Clause of Fourteenth Amendment (Friedman 2005)
In that context, profiling takes the form of statistical information of past offenders used to generate demographic and personal identifying criteria based on various commonalities between offenders of specific types of crimes. While psychological profiling does not justify or permit the violation of due process rights of any individual based solely on matching the criteria associated with the unknown suspect, the information is used appropriately to narrow the field of potential subjects of further investigation (Shusta, et al
Police profiling refers to the unconstitutional practice of selecting subjects for police enforcement by virtue of their characteristics; issues in that regard arise most commonly in connection with racial background, cultural heritage, and apparent social class. Traditionally, traffic enforcement has generated the vast majority of profiling allegations, because of the ubiquitous nature of driving in American society as well as the dynamic associated with operational mechanics of initiating traffic stops at the police officer's autonomous discretion and choice with regard to selection of violators to pursue (Peak 2002)
It is expressed in the Fifth Amendment to the Constitution with respect to the federal government and, since 1914, has been applied to the states through the Equal Protection Clause of Fourteenth Amendment (Friedman 2005). Equal protection prohibits differential treatment under the law, which applies, in principle, to being subjected to police investigation and detention predicated on personal characteristics rather than specific criminal behavior or reasonable suspicion thereof (Schmalleger 1997)
In reality, criminal profiling tends to be far less spectacular, involving the analysis of various crime scene, environmental, and psychological factors to help investigators create a narrower pool of suspects to investigate. Furthermore, much controversy has been attached to this technique, since the main critique against it is there is a marked lack of validity to support it (LaMance, 2011)
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
, this method investigating and solving criminal acts especially those of violent nature is always backed by logic, proofs, solid and tangible evidences. Presentation of these proofs and evidences help to ensure that the three major goals of criminal profiling are achieved (Holmes and Holmes 9): To provide the criminal justice system with a social and psychological assessment of the offender; To provide the criminal justice system with a psychological evaluation of belongings found in the possession of the offender; and To provide interviewing suggestions and strategies
Of particular interest in the criminal justice system is how violent crimes are solved via criminal profiling or oftentimes referred to as psychological profiling. Criminal profiling is the process of using available information about a crime and crime scene to compose a psychological portrait of the unknown perpetrator of the crime (Muller 234)
The premise holds that elements of the crime scene represent the offender's personality and approach aims to provide the most likely characteristics, both personality and demographic, possessed by the unknown offender for the police investigation. (Young 15)
