CCP Geographic Profiling & Mapping 3 — Questions and Answers
Question 1: Which concept describes the geographic area where an offender is comfortable operating and has experiential knowledge from daily activities?
- Crime attractor zone
- Activity space / awareness space (Correct answer)
- Criminal opportunity field
- Predatory search radius
Correct answer: Activity space / awareness space
Awareness space (or activity space) is the geographic area an offender knows well through routine activities like work, shopping, and recreation.
Question 2: Hot spot mapping using kernel density estimation (KDE) produces:
- A list of suspects ranked by proximity to crime scenes
- A smooth, continuous surface showing crime density across a geographic area (Correct answer)
- A discrete grid of crime counts per census block
- A network map of offender movement patterns between locations
Correct answer: A smooth, continuous surface showing crime density across a geographic area
KDE generates a continuous probability density surface that smooths point data into a raster showing relative crime concentration across space.
Question 3: The 'circle hypothesis' in geographic profiling, associated with Canter and Larkin, proposes that:
- All serial offenders operate within a fixed 5-mile radius from their home
- The offender's home is likely located within a circle whose diameter spans the two most distant crime sites (Correct answer)
- Crime series form circular patterns due to offender evasion tactics
- Victims are selected from a circular zone around transit hubs
Correct answer: The offender's home is likely located within a circle whose diameter spans the two most distant crime sites
Canter and Larkin's circle hypothesis states that the offender's home base typically falls within a circle defined by the two furthest crime locations as its diameter.
Question 4: STAC (Spatial and Temporal Analysis of Crime) is a software tool used to:
- Generate DNA phenotyping predictions of offenders
- Identify statistically significant crime clusters using ellipse-based analysis (Correct answer)
- Map patrol routes based on officer response times
- Predict future crime dates using regression modeling
Correct answer: Identify statistically significant crime clusters using ellipse-based analysis
STAC identifies statistically significant clusters of crime events using spatial ellipses to delineate hot spots.
Question 5: A 'crime attractor' in environmental criminology is best defined as:
- A location that is well-lit and monitored, deterring criminal activity
- A place that draws offenders because of known criminal opportunities (Correct answer)
- A psychological trigger that increases an individual's propensity toward crime
- A high-density residential area with elevated crime rates
Correct answer: A place that draws offenders because of known criminal opportunities
Crime attractors are specific places known to potential offenders for their criminal opportunities, drawing offenders who travel specifically to exploit them.
Question 6: When analyzing serial arson using geographic profiling, which anchor point is most commonly identified as the offender's base?
- The most recently targeted location
- Residence or workplace, depending on the offender's profile (Correct answer)
- The geographic centroid of all fire locations
- The nearest fire station to the majority of fires
Correct answer: Residence or workplace, depending on the offender's profile
Serial arsonists typically anchor to their residence or workplace, and the geographic profile attempts to identify which anchor point is generating the crime pattern.
Question 7: The mean center of crime locations is best used in geographic profiling to:
- Identify the exact location of the offender's residence
- Provide an initial, simple estimate of the probable offender anchor area (Correct answer)
- Determine which crime location was committed first in a series
- Establish the geographic extent of an offender's hunting ground
Correct answer: Provide an initial, simple estimate of the probable offender anchor area
The mean center provides a basic starting estimate of the central tendency of crime locations, offering a rough anchor area for further refined analysis.
