Study Notes

Tactical Crime Analysis

  • Tactical analysts work with data sets covering a period of 2 weeks.
  • Pattern identification involves collecting information from various sources to identify similarities among crimes.
  • Commonality: Exact matches between crime patterns.
  • Similarity: Close matches between crime patterns.
  • Clearance rate measures the success of solving crimes (number of cases cleared/total number of cases x 100).
  • MO Summary is a form of pattern analysis that manually synthesizes information from various sources (occurrence reports, tips, social media) to understand the "who, what, where, and how" of a crime.

Crime Pattern Types

  • Series: A group of similar crimes believed to be committed by the same offender.
  • Spree: A series of crimes committed in a short period, often involving violence (killing spree).
  • Hot Prey: Crimes targeting victims with specific characteristics and behaviors (e.g., gang killings).
  • Hot Product: Crimes targeting specific types of property (e.g., espionage).
  • Hot Place: Crimes committed in a specific location.

Analyzing Crime Frequency

  • Tactical analysts focus on short-term trends (24 hours to 3 months), while strategic analysts examine long-term trends (3 months to decades).
  • Two primary methods for analyzing crime frequency:
    • Frequency Distribution: Analyzing the occurrence of values within a dataset based on predetermined categories.
    • Crosstabulation: Examining the relationship between two or more variables.
  • Data is often grouped by week or month to identify longer-term patterns.
  • This information is valuable for crime reduction measures, resource allocation, and policy formulation.

Weighted Time Span Analysis

  • Analyzes temporal patterns between crimes in series.
  • Considers factors like seasonality, weather, school attendance, and work schedules, which can influence crime frequency.

Trend Comparisons

  • Comparing trends across crime categories, different jurisdictions, or other relevant factors provides valuable insights.
  • Temporal intervals can be categorized as:
    • Accelerating: Decreasing time between incidents.
    • Decelerating: Increasing time between incidents.
    • Constant: Consistent time between incidents.
    • Random: No discernible pattern.
  • Tempogram: Graphical representation of temporal intervals between crime events in a series.

Strategic Crime Analysis

  • Focuses on long-term crime reduction strategies.
  • Utilizes both primary and secondary data sources to understand the context of crime events.
  • Primary data: Directly collected information (e.g., police reports).
  • Secondary data: Existing data from other sources (e.g., census data).

Traditional vs. Environmental Criminology

  • Traditional Criminology: Examines biological, psychological, and sociological factors to understand why individuals become criminals.
  • Environmental Criminology: Focuses on the situational factors that contribute to crime.
  • Analyzes how specific environments create opportunities for crime.

Crime Triangle

  • Identifies the essential elements that contribute to criminal activity:
    • Offender: The perpetrator of the crime.
    • Target/Victim: The person or object targeted by the crime.
    • Place: The location of the crime.

Routine Activities Theory

  • Crimes occur when the activity spaces of potential offenders and potential victims/targets overlap.
  • Offenders often commit crimes within or close to familiar locations.
  • Pareto Principle: A small number of locations account for a large proportion of crime events (80/20 rule).
  • Law of Crime Concentration: 50% of crime is concentrated in a small percentage of locations.

True Repeats

  • Occurs when a target is victimized on multiple occasions by the same type of crime, likely by the same offender.
  • Example: A person being assaulted multiple times at the same location.

Tactical Analysis & Pattern Identification

  • Tactical analysts use data from the past two weeks to identify patterns.
  • Pattern analysis involves grouping similar cases based on similarities and commonalities.
  • Commonalities indicate exact matches, while similarities indicate close matches within a crime pattern area.
  • Clearance rate measures the success of solving crimes. This is calculated by dividing the number of cleared cases by the total number of cases and then multiplying by 100.
  • An MO summary is a type of pattern analysis that involves combining information from various sources like occurrence reports, tips, and social media.

Types of Crime Patterns

  • Series: A group of similar crimes likely committed by the same offender.
  • Spree: A series of crimes committed in a short period, often involving violence, usually classified as a killing spree.
  • Hot Prey: Crimes targeting individuals with shared characteristics and behaviors, such as gang killings.
  • Hot Product: Crimes involving the theft of specific types of property, such as espionage.
  • Hot Place: Crimes concentrated in a particular location, often committed by the same offender or group.

Analyzing Crime Frequency

  • Tactical analysts analyze crime frequency within 24 hours to three months to identify short-term trends.
  • Strategic analysts analyze data for three months to a decade or longer to identify long-term trends.
  • Frequency Distribution: A method for visualizing trends by grouping data into categories and analyzing the frequency of occurrences within those categories.
  • Crosstabulation: A table that displays the relationship between multiple variables, aiding in trend analysis.
  • Grouping frequency by week and month helps detect longer-term patterns in crime frequency.

Weighted Time Span Analysis

  • Seasonality: The influence of factors like weather, school attendance, and work schedules on crime frequency.

Trend Comparisons

  • Comparing monthly or yearly trends to other crime categories, other jurisdictions, or other relevant benchmarks helps in assessing the significance of the observed trend.

Temporal Intervals

  • Accelerating: Decreases in the time between incidents.
  • Decelerating: Increases in the time between incidents.
  • Constant: Stable intervals between incidents.
  • Random: No discernible recurring pattern.
  • Tempogram: A visual representation of the temporal intervals between crimes in a series.

Crime Analysis: The Big Picture

  • Overarching Purpose: To improve safety and security by reducing crime.
  • Crime Prevention: Proactive measures to eliminate opportunities or discourage criminal activity.
  • Crime Analysis: Not involved in crime scene investigation, forensic profiling, or analysis of physical evidence.

Tactical vs. Strategic Crime Analysis

  • Tactical Crime Analysis: Short-term analysis (24 hours to 3 months) to provide immediate support for cases.
  • Strategic Crime Analysis: Long-term (3 months to decades) analysis focused on crime reduction objectives. Utilizes primary and secondary data, facts, and theories.

Criminological Perspectives

  • Traditional Criminology: Examines the biological, psychological, and sociological factors that contribute to criminal behavior.
  • Environmental Criminology: Focuses on the situational factors that influence crime occurrence rather than the individual motivations of offenders.
  • Crime Triangle: A model that emphasizes the interplay between the offender, the target/victim, and the place, emphasizing the role of opportunity in crime.

Routine Activities Theory and the Crime Pattern Theory

  • Routine Activities Theory: Suggests that crime occurs when motivated offenders, suitable targets, and a lack of capable guardianship converge.
  • Crime Pattern Theory: A central concept in environmental criminology, it proposes that crime opportunities arise when the activity spaces of potential offenders and victims overlap.
  • Offenders: Tend to commit crimes in areas familiar to them.
  • Pareto Principle (80/20 Rule): A small number of places account for a large proportion of crime.
  • Law of Crime Concentration: A specific location accounts for a significant percentage of crimes.

Repetitive Crimes

  • True-repeats: The same target is victimized multiple times by the same crime type.
