profiling based on experience and “gut feelings” rather than on research and statistical data
clinical profiling
the ____ profiling approach is case focused and tries to infer characteristics of an offender from the analysis of evidence gathered from a specific crime or series of crimes
clinical
a procedure that employs statistical group data based on prior offenders to identify an individual offender who committed similar crimes
actuarial profiling
the naturally occurring rate of a phenomenon within a given population
base rate
the process of identifying personality traits, behavioral tendencies, and demographic variables of an offender based on characteristics of the crime
profiling
process of determining the likelihood and seriousness of harm carried out by a person who displayed warning signs, such as making veiled oral or written threats
threat assessment
a process to evaluate individuals who have violated social norms or displayed bizarre behavior, particularly when they appear menacing or unpredictable
risk assessment
controversial and potentially illegal method that tries to identify an offender based on characteristics of prior offenders who have committed similar crimes
suspect-based profiling
illegal singling out of someone (ex. by law enforcement) solely on the basis of his or her race or ethnicity
racial or ethnic profiling
a type of profiling that focuses on the location of the crime and how it relates to the residence and/or base of operations of the offender
geographic profiling
one of several forms of profiling which refers to examining features at the scene of the crime to discern characteristics about the offender (also referred to as offender profiling)
crime scene profiling
any behavior that goes beyond what is necessary to commit the crime
signature
____ signature is left deliberately by the offender, whereas ____ signature is beyond the offender’s awareness
crime scene signature; psychological signature
the intentional alteration of a crime scene before the arrival of the police
