Crime Analysis???

What Is It?

Who Uses It?

What Information Does It Provide?

How Does It Impact Society?

What Specific Types Of Crime Analysis

Are Being Studied?

2

General Definition

Crime Analysis is the logical examination of crimes that have penetrated preventative measures.

Crime Analysis also provides a proactive approach to security and law enforcement for the implementation of new crime prevention techniques.

3

Goals of Crime Analysis

To reduce crime on property.

To evaluate and aid in the selection of security and crime prevention measures.

To justify crime prevention expenditures.

To provide a system of monitoring the effectiveness of security and crime prevention measures.

To provide a continual evaluation system of the property’s crime situation.

To reduce the liability of property owners and their agents (property managers).

4

Crime Analysis &

Circle Of Control/Influence

Crime Analysis helps differentiate between a property manager’s area of control (Circle Of Control) and the areas over which managers have influence (Influence Of

Control).

Property Managers are those people who own or contractually manage property that is public or private.

Circle Of Influence

Circle Of Control

5

Descriptive Analysis of

COC

Using the building manager scenario as an example, our manager is responsible for the building’s operation, the common areas, and the parking garage, which constitute his Circle Of Control.

6

Descriptive Analysis of COI

An example of an area within his Circle Of

Influence is the property next door, a strip used daily by his tenants. The proximity of this strip center to his building, its use by his tenants, and his relationship with that center’s management place this facility within his Circle Of Influence. Though he is not responsible for this facility, it does affect his property’s security and vice-versa.

7

Legal Ramifications

Involving Premises

Security

A Premises Security lawsuit is a civil action brought on behalf of a person seeking damages for negligent security against the owners and their agents.

Generally, three elements must be met in order for the plaintiff to prevail. These elements are, duty, breach of duty, and proximate cause.

8

Crime Analysis

Data Sources

Statistics represent criminal activity in the form of numbers, comparable to an inventory, in which the Crime Analysis task is the reformation of that activity as a tangible tool for risk management.

9

Calls For Service (CFS)

The primary data set is Calls For Service (CFS), which serves as crime analysis’ basis and provides for the most accurate portrayal of criminal and other activity at a property. CFS consist of every report of crime, suspected crime, and activity called on to police from a property.

Research has concluded that unreported crime accounts for a 10% higher crime index, though this is highly dependent on the type of crime under observation. Despite the exclusion of unreported crime, CFS still provides conclusive illustrations of criminal activity on a property.

10

Types Of Data Reports

Offense ReportsGenerated when police discover a crime independent from a call into the

911 system.

Uniform Crime ReportsThe most exhaustive and geographically comprehensive crime statistics available in the United States. The FBI is responsible for the publication of the UCR.

National Crime Victimization SurveyInitiated by the United States Census Bureau and Law

Enforcement Assistance Administration in 1972, include characteristics of crime victims, such as age, sex, ethnicity, and martial status.

11

Additional Data Reports

Demographic DataInclude statistical data in reference to population counts, socioeconomic levels, education levels, and personal traits of the population.

Security ReportsInclude reports of criminal activity and other incidents (parking, loitering, security breaches). Management may generate these reports directly or through a contracted security service.

National Incident~Based Reporting System

(NIBRS)The future of Crime Analysis and a new measure of crime is found in the NIBRS.

12

Geographic Levels Of

Analysis

Is a hierarchy that denotes the levels of

Geographic Analysis, ranging from the specific to the general.

It is geared toward being as site~specific as possible displaying the importance and relationship between each level.

Property

Census Tract

13

Geographic Levels Of

Analysis~Hierarchy Pyramid

Property- Is the fundamental level of analysis that refers to a single address over which the manager has absolute control.

Census Tract- Geographic areas defined by the

U.S. Census Bureau for population and geographic purposes.

Beat, District, or Precinct- Patrol Beats are common geographical zones that law enforcement allocate resources. Districts and Precinct’s are areas in which command centers are grouped.

14

Geographic Levels Of

Analysis~Hierarchy Pyramid

Continued

Crime Statistical Reporting Area- Statistical Reporting Area

(RA) is a uncommon level of analysis. Generally, RA’s are small homogenous areas created for the sole purpose of supporting crime data collection. Uncommon because it creates inconsistency across jurisdictions.

City/County- Encompass crime information for the entire law enforcement jurisdiction. City and County data are on the middle ring of the Circle Of Influence.

Metropolitan Statistical Area (MSA)- Account for approximately 76% of the total U.S. Population. This is considered the outer of the Circle Of Influence. Created purely for Crime Statistical purposes.

15

Geographic Levels Of

Analysis~Hierarchy Pyramid

Continued

State- Similar to city and county data, state can be found in the UCR and include information for the entire state. Information is available through the State Police.

Nation- Crime Stats for the Nation are available through the UCR program, via actual crime information and estimations for the occasional jurisdiction that are not involved in the program.

16

Crime Statistics Today

BJS conducts the annual National Crime

Victimization Survey (NCVS).

Today’s statistics originate from the Bureau of

Justice Statistics (BJS) and the Federal Bureau of

Investigation (FBI).

FBI publishes data that is summarized in the

Uniform Crime Reporting Program (UCR) and its incident-driven National Incident Based

Reporting System (NIBRS).

17

The Uniform Crime Reporting

Program

Started by the FBI in 1929 in response to a national initiative undertaken by the

International Association of Chiefs of Police

(IACP). The objective was to develop a set of consistent crime statistics for policymakers and police agencies to use throughout the country.

18

The Structure of UCR

Initial data was structured in terms of seven major offense categories: Murder, Rape,

Robbery, Aggravated Assault, Burglary,

Larceny, and Motor Vehicle Theft.

These crimes are called, Part 1 Offenses.

When averaged together and compared with the country’s population, it forms the FBI’s

Crime Index.

19

The FBI’s “Crime Clock”

Part 1 Offenses, showing the number of crimes reported in 1999 and 1995.

The Crime Clock subdivides Part 1

Offenses into two categories: Violent

Crime and

Property Crime.

20

Problems with the UCR

The most significant methodological feature of the UCR is indicated by its name. It is a reporting program. In other words, only crimes that are reported to police are included in these statistics.

The most underreported crime is larceny, because petty theft may never make it into official police reports.

NIBRS: The New UCR

Recently, the UCR received an overhaul funded by the Criminal Identification Technology Act of

1998. The National Incident-Based Reporting

System (NIBRS), a new statistical system, was derived from the UCR.

The NIBRS was designed to gather detailed data on weapons, injuries received, crime locations, victims, offenders, sex, age, race, and much more.

NIBRS CONTINUED

The NIBRS has 22 crime categories in which make up 46 specific crimes called

11 “Group B Offenses.” Group B Offenses only offer data pertaining to reported arrest data.

The goal of the NIBRS is to make data reporting and data retrieval easy and readily available.

Problems With The NIBRS

The transition process is not moving as quickly as planned. Scheduled to be fully in place by 1999.

It is not being widely accepted by local law enforcement due to limited manpower in managing the transition process.

The NIBRS offers much more than past statistical programs. However, it cannot be fully critiqued until it is fully implemented.

National Crime

Victimization Survey

NCVS consists of information elicited through interviews with members of randomly selected households throughout the nation.

NCVS data is gathered by the U.S. Census

Bureau personnel who survey approximately

49,000 households consisting of about 101,000 people.

The NCVS uncovers a large number of crimes that may not have been reported, therefore regarded by researchers as a more accurate measure of incidence crime.

Problems With The NCVS

The NCVS can be criticized for possible over-reporting. No attempt is made to verify the actual occurrence of any of the crimes reported to NCVS interviewers.

Individuals being interviewed sometimes embellish crime reports to gain attention and/or sympathy.

46

NCVS vs. UCR

The collection of NCVS data began in 1972. It is newer than the FBI’s UCR established in 1929.

Recent changes have resulted in the inability to easily compare NCVS findings with past findings.

The UCR offers a more consistent system in comparing data due to more agencies being involved.

The NCVS is based on interviews per household.

The UCR is based on factual cases.
