CIAC Crime Pattern Recognition & Analysis 2 — Questions and Answers
Question 1: Which analytical technique uses geographic anchor points to estimate where a serial offender most likely lives or works?
- Choropleth mapping
- Geographic profiling (Correct answer)
- Crime scripting
- Temporal displacement analysis
Correct answer: Geographic profiling
Geographic profiling uses spatial analysis of crime sites to generate a probability surface indicating the most likely offender anchor point such as home or workplace.
Question 2: A crime analyst notices that residential burglaries cluster on Fridays between 3–6 PM near a high school. This is an example of what type of pattern?
- Spree pattern
- Temporal-spatial convergence (Correct answer)
- Target hardening response
- Crime displacement
Correct answer: Temporal-spatial convergence
Temporal-spatial convergence describes a pattern where crimes cluster at specific times AND locations, here tied to school dismissal hours.
Question 3: The 'near repeat' phenomenon in crime pattern analysis refers to what observation?
- Offenders who reoffend within 30 days of release
- Locations near a recently victimized target face elevated risk for a short period (Correct answer)
- Repeat calls for service at the same address
- Offenders who use the same MO in consecutive crimes
Correct answer: Locations near a recently victimized target face elevated risk for a short period
Near repeat victimization shows that properties spatially close to a recently burglarized target face significantly elevated risk for days or weeks afterward.
Question 4: When comparing crime series to crime patterns, which distinction is most accurate?
- A series involves one offender; a pattern involves unrelated crimes sharing environmental characteristics (Correct answer)
- A series is geographic; a pattern is behavioral
- A series involves property crime; a pattern involves violent crime
- A series spans multiple jurisdictions; a pattern is single-jurisdiction only
Correct answer: A series involves one offender; a pattern involves unrelated crimes sharing environmental characteristics
A crime series is linked to a single offender committing multiple offenses, while a crime pattern refers to clusters of crimes sharing time, place, or target type regardless of offender identity.
Question 5: Which statistical method is most commonly used to identify statistically significant spatial clusters of crime rather than random distribution?
- Linear regression
- Kernel density estimation
- Chi-square goodness of fit
- Moran's I spatial autocorrelation (Correct answer)
Correct answer: Moran's I spatial autocorrelation
Moran's I measures spatial autocorrelation to determine whether crime events cluster, disperse, or distribute randomly across an area.
Question 6: A crime analyst finds that auto thefts declined in one neighborhood after a crackdown but increased in an adjacent neighborhood. This is best described as:
- Crime prevention through environmental design
- Diffusion of benefits
- Crime displacement (Correct answer)
- Situational crime prevention
Correct answer: Crime displacement
Crime displacement occurs when enforcement pressure in one area causes offenders to shift their activities to nearby locations, times, targets, or methods.
Question 7: Which element is NOT typically used to link crimes in a behavioral-MO comparison for series identification?
- Entry method
- Time of day
- Offender's height and weight estimate (Correct answer)
- Target selection criteria
Correct answer: Offender's height and weight estimate
Physical descriptions of suspects are investigative leads, not MO elements; MO linking relies on behavioral choices such as entry method, target type, and timing.
