The FBI method of profiling is a system created by the Federal Bureau of Investigation (FBI) used to detect and classify the major personality and behavioral characteristics of an individual based upon analysis of the crime or crimes the person committed.〔Douglas, Ressler, Burgess & Hartman, 1986〕〔Turvey, 1999〕 One of the first American profilers was FBI agent John E. Douglas, who was also instrumental in developing the behavioral science method of law enforcement.〔(Mindhunters, Inc. | Perspectives on Profiling, Investigation & Criminal Justice with John Douglas & Mark Olshaker )〕 == Profiling phases == The process this approach uses to determine offender characteristics involves: #An assimilation phase where all information available in regard to the crime scene, victim, and witnesses is examined.〔Jackson & Beckerian, 1997〕 This may include photographs of the crime scene, autopsy reports, victim profiles, police reports, and witness statements. #The "classification stage", which involves integrating the information collected into a framework which essentially classifies the murderer as "organized" or "disorganized". Organized murderers are thought to have advanced social skills, plan their crimes, display control over the victim using social skills, leave little forensic evidence or clues, and often engage in sexual acts with the victim ''before'' the murder.〔Douglas et al., 1986; Jackson et al., 1997〕 In contrast, the disorganized offender is described as impulsive, with few social skills, such that his/her murders are opportunistic and crime scenes suggest frenzied, haphazard behavior and a lack of planning or attempts to avoid detection. They might engage in sexual acts after the murder, because they lack knowledge of normal sexual behavior.〔Woodworth & Porter, 2002〕 #Following the classification stage profilers attempt to reconstruct the behavioral sequence of the crime, in particular, attempting to reconstruct the offender's modus operandi or method of committing the crime.〔Jackson et al., 1997〕 #Profilers also examine closely the offender's “signature” which is identifiable from the crime scene and is more idiosyncratic than the modus operandi—the signature is what the offender does to satisfy his psychological needs in committing the crime.〔Woodworth et al., 2002〕 #From further consideration of the modus operandi, the offender's signature at the crime scene, and also an inspection for the presence of any staging of the crime, the profiler moves on to generate a profile. This profile may contain detailed information regarding the offender's demographic characteristics, family characteristics, military background, education, personality characteristics, and it may also suggest to the investigator the appropriate interview/interrogation techniques to adopt.〔 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「FBI method of profiling」の詳細全文を読む スポンサード リンク
