The limitations of arrest strategies

Even though many police officers profess to wanting to
catch the criminal elite, they are constrained by an
organizational system that rewards them for the volume
of arrests rather than the quality of their captures


As a result of observations of over 300 crack dealers, and
interviews with over 120, Johnson and Natarajan estimate that
experienced and higher-level dealers can minimize the risk of
arrest to one for every thousand drug transactions or more
(See Johnson and Natarajan 1995: 54)
Conviction rates in the UK from suspicious transaction reports
during the early 1990s were as low as one for every thousand
suspicious reports
(See Levi, 2002)

Why don’t politicians embrace prevention?

Steve Lab (2004) points out why there is a general
lack of enthusiasm for prevention from policymakers.
Politicians prefer programs with:




immediate results
focus on outcomes that can be counted
a sensationalist streak
an eye to the immediate problems of the day
Defining reduction, disruption or prevention

Crime reduction


Disruption


Brings ‘net benefits after considering the impact of
displacement and diffusion of benefits, fear of crime and the
impact from other programs that may have contributed to any
specific crime reduction activity’ (Chainey and Ratcliffe 2005:
19)
Disruption ‘occurs when the business is hampered for a period
of time, normally as a result of law enforcement action, but is
not permanently disabled’ (EUROPOL 2006: 17)
Crime prevention

Involves any activity by an individual or group, public or private,
which attempts to eliminate crime either before it occurs or
before any additional activity results (Lab 1988)
Levels of crime prevention

Primary prevention


Secondary prevention


Identifies conditions of the physical and social environment that
create, precipitate or provide opportunities for criminal
behavior (Brantingham and Faust 1976)
Aims to reduce risks associated with those people vulnerable to
involvement in crime, and to ameliorate the chance of high-risk
offenders developing more serious criminal activities.
Tertiary prevention

Deals with actual offenders and involves ‘intervening with the
lives of these offenders in a manner that prevents them from
committing other crimes and includes arrest and prosecution,
reform and rehabilitation, and institutional education programs’
(Chainey and Ratcliffe 2005: 17)
Levels of crime prevention: ILP relevance

Primary prevention


Secondary prevention


Used to tackle the systemic weaknesses that offenders
exploit so that more strategic problem-solving can take
hold
Provides opportunities to identify priorities for resource
allocation and targeting
Tertiary prevention

Prevention benefits from the arrest and prosecution of
high-risk, prolific and persistent offenders
The changing leadership role

Most police commanders have been groomed for
leadership positions by subjecting them to training
and experiences that are not related to crime
reduction


‘We have people in leadership and management positions
who were never expected to do the job I’m asking them to
do’
(New Zealand Police District Commander quoted in
Ratcliffe 2005: 449)
The limitations of lawyers


In many US jurisdictions, the chief law enforcement
officer has a legal background (district attorney or
county prosecutor)
This often prevents them from understanding the
benefits of crime disruption or prevention

‘Although the gradual acceptance of prevention as the
primary purpose of intelligence may precipitate
improvement, law enforcement has a long history of
strategies that respond to a current problem but rarely
prevent or control an emerging or anticipated threat’
(Higgins 2004: 72)
Does police targeting prevent crime?

Unfocused increases in police numbers appears to be
relatively ineffective

10 per cent increase in police numbers would, on average,
result in a 3 per cent reduction in the major crime types
for a city
• Evidence from a study of 49 states and 56 cities conducted by
Marvell and Moody, 1996

‘Hiring more police officers did not play an independent or
consistent role in reducing violent crime in the United
States’ (Eck and Maguire 2000: 217)
Police impact on crime

Limited or no value






Unfocused increases in police numbers
Targeted patrols at drug corners
Arrests of some juveniles for minor offences
Drug market arrests
Community policing with no clear crime-risk factor focus
Positive impact




Targeted patrols in (non-drug) crime hotspots
Civil code violations and nuisance legislation applied to drug
houses
Proactive arrests of serious repeat offenders
Combine enforcement with prevention strategies
Concentrating on the 6 per cent


The 6% that commit 60% of all crime
New South Wales Police Compstat-like process
encouraged local police commanders to focus on




Crime hot spots and hot times
Spend more time searching people for illegal weapons
Target recidivist offenders
OCR process shown to reduce crime and



a burglary was prevented for every two arrests,
a vehicle theft was prevented for every five arrests, and
a robbery was prevented for every 30 arrests
(See Chilvers and Weatherburn 2001a: 11)
University of Maryland review

Successful strategies




Incapacitating offenders who continue to commit crimes at
high rates
Family therapy by clinical staff for delinquent and predelinquent youth
Short-term vocational training programmers for older male
ex-offenders no longer involved in the criminal justice
system
Prison-based therapeutic community treatment of druginvolved offenders
University of Maryland review

Promising tactics (but that have to be evaluated further)





Gang violence prevention focused on reducing gang
cohesion
Battered women’s shelters for women who take other
steps to change their lives
Housing dispersion programs
Enterprise Zones
Intensive, residential training programs for at-risk youth
University of Maryland review

Unsuccessful tactics





Gang community mobilization against crime, in high-crime,
inner-city poverty areas
Gun buy-back programs operated without geographic
limitations on gun sources
Summer job or subsidized work programs for at-risk youth
Short-term, non-residential training programs for at-risk
youth
Emphasized specific deterrence such as shock probation
and Scared Straight
“Whether the motivation is religious fundamentalism, antigovernment sentiment, or the disaffected loner, radicalized
groups or individuals are increasingly perpetrating terrorism.
A substantial attack upon U.S. soil is increasingly likely. The
answer rests with prevention. …
The only way to prevent radicalization is to end the
conditions that foster it. When efforts at prevention are
unsuccessful or impractical, a fully trained and seamlessly
integrated public safety force is required to recognize
preincident indicators and develop interdiction, disruption,
or arrest strategies.”
(Bratton 2007: 6-7)
