4 Types of Analysis(The soap opera theory . . .)

  • Crime

    (or: Who’s doing what TO whom . . .)

  • Intelligence

    (or: Who’s doing what WITH whom . . .)

  • Operations

    (or: Who’s using what where . . .)

  • Investigations

    (or: Let’s find out who’s doing what to whom, where, why, and with what . . . . .)


What is crime analysis anyway l.jpg
What Is Crime Analysis, anyway?

A systematic process of collecting, categorizing, analyzing, and disseminating timely, accurate, and useful information that describes crime patterns, crime trends, and potential suspects.


What is intelligence analysis l.jpg
What Is Intelligence Analysis?

The systematic collection, evaluation, analysis, integration, and dissemination of information on criminals, especially related to their association and their identification with criminal activity of an organized nature.


What is operations analysis l.jpg
What is Operations Analysis?

The study of police service delivery problems, undertaken to provide commanders and managers with a scientific basis for decisions and/or actions aimed at improving operations or deployment of resources.

Crime Pattern - The occurrence of similar offenses in a defined geographic area, usually defined by administrative boundaries.

Crime Series - A crime pattern where there is reason to believe the same person(s) committed the crimes.

Crime Trend - A recognizable general tendency regarding recurring patterns of crime which is revealed over a period of time. A trend may involve any one of the crime pattern factors or any combination of the factors.


Types of crime analysis l.jpg
Types of Crime Analysis

  • Administrative

  • Strategic

  • Tactical


Administrative crime analysis is l.jpg
Administrative Crime Analysis is. .

. . . .used for policy development and resource justification.

  • Cost-effectiveness studies

  • Program evaluations

  • Budget justifications


Strategic crime analysis is l.jpg
Strategic Crime Analysis is . . .

. . . used for identifying problems and potential approaches for dealing with them.

  • Exception Reports - identifies unusual levels of activity in an area over a month-to-month or annual time period.

  • Crime Trend Forecasts - projects future trends in various types of crimes based on past experience.

  • Resource Allocation Proposals - suggests shifts of resource(s) to meet new crime related service demands.

  • Situational Analysis - provides information about crime problems and the environment in which they are occurring. Often referred to as Beat Profiling.


Tactical crime analysis is l.jpg
Tactical Crime Analysis is . . .

. . . used to take action designed to address specific types of crimes and offenders.

Logistical issues l.jpg
Logistical Issues

  • Organizational placement

    • Planning/Research?

    • CEO’s office?

    • Investigations?

    • Patrol?


Slide16 l.jpg

  • Physical location of CAU

    • Maximize officer contact.

    • Close to information sources.

    • Roll call rooms have been used in some jurisdictions.

    • Consider amount of space, equipment,

      and supplies needed.


Staffing l.jpg

  • How many

  • Clerical and support needs

How is crime analysis done l.jpg
How Is Crime Analysis Done?

  • Collect the data

  • Collate the data

  • Analyze the data

  • DISSEMINATE the data!

  • Feedback/evaluation


Data collection l.jpg
Data Collection

Gathering “crime specific” elements of information about crime problems, primarily from

  • Offense reports

  • Arrest reports

  • Field interviews


Data collection23 l.jpg
Data Collection

Data must be:

  • Standardized

  • Usable

  • Good quality

  • Format facilitating collection


Crime reports l.jpg
Crime Reports

  • Geographic factors

  • Time factors

  • Victim/target descriptors

  • Property loss descriptors

  • Physical evidence descriptors

  • Solvability factors

  • Specific MO factors


Fi reports l.jpg
FI Reports

  • Geographic factors

  • Time factors

  • Subject descriptors

  • Subject vehicle descriptors

  • Names of associates w/subject

  • Reason(s) for FI


Arrest reports l.jpg
Arrest Reports

  • Geographic factors

  • Time factors

  • Victim/target descriptors

  • Recovered property descriptors

  • Suspect vehicle descriptors


Data collation aka target crimes l.jpg
Data Collation(aka Target Crimes)

Burglary

Planning considerations l.jpg
Planning Considerations

  • How many/what type of target crimes

  • Frequent enough to produce recognizable patterns

  • Does CAU have personnel/time necessary to build/maintain files

  • Specific enough to be categorized

  • Designed to facilitate retrieval

  • Relationships established

Analysis Process

. .looking for similarities and related facts.

Two major types:

  • Geographic concentration
