3Patterns and Trends
Weapons are more likely to be used in some types
of violent crime than others (in 20 of all
violent crimes overall).
4Patterns (cont.)
- In any given year, firearms are involved in ½ of
all suicides and 2/3 or more of homicides (NRC,
2005). - Age and Race The risk of death is elevated for
young people (ages 15-34), particularly black
males. - Gender 83 of gun crime victims are males.
- Guns Estimated 258,000,000 firearms in U.S.
(NRC, 2005)
5Trends Number of crimes committed with firearms
declined dramatically after 1993.
6Offenders
- 90 of firearm homicides committed by males.
- Offense rates are highest for ages 18-24.
- The increase in juvenile homicides witnessed in
the mid-1980s was entirely firearm-related. - Sheley Wright
- Juveniles report easy access to guns -- only 35
said it would be difficult. - 83 of juveniles incarcerated in secure detention
centers and 22 of urban high school students
possessed guns. - The main reason given for carrying a gun was
self-protection.
7Offenders (cont.)
- FIREARM ACQUISITION AND USE
- Wright Rossi (1985)
- Interviewed 1,874 incarcerated felons. Of these,
184 reported firing a gun while committing an
offense. - The most commonly reported motivations for using
a gun included to protect myself (48), to
scare the victim (45), and to kill the victim
(36). (Categories not mutually exclusive) - 1991 Survey of State Prison Inmates (Beck, 1993)
- Interviewed 14,000 inmates
- The most frequently reported reasons for using a
gun were to scare the victim (54), for
protection (30), to kill the victim (14), and
to get away (12). - SOURCES OF GUN ACQUISITION
- Inmates most frequent source was family or
friends (44), followed by illegal gun markets
(26), retail outlets (21), and other (9).
8Explanations
- Symbolic Interaction Theory
- Luckenbill Disputes become violent through a
series of interpersonal exchanges. - A situated transaction refers to an interaction
between people in a specific setting, time, and
social context. - The presence of a weapon during a dispute greatly
increases the likelihood of its use. - Homicides typically centered on some conflict
that escalated over time, and resulted in
attempts by one or both parties to "save face" at
the other's expense.
9Routine Activities and Illegal Markets
- Routine activity patterns influence crime rates
by affecting the convergence in space and time
of (1) motivated offenders, (2) suitable
targets, and (3) the absence of capable
guardians. - Offenders commit offenses near places where they
spend most of their time, and major pathways in
between. - Victims are victimized near places where they
spend most of their time, and major pathways in
between. - Sherman et al. (1989) Places, like people, have
their own routine activities. - Hot spots Over half of all calls to police were
to only 3.3 of all places. - Illegal markets in certain places (e.g.,
prostitution, drug sales) create their own
routine activities.
10Cultural Theories and Firearm Availability
- Proportion of households owning a gun has
remained stable at about 50 for three decades. - Rates of gun ownership are highest in rural areas
and small towns, higher for whites than blacks,
highest in the South, and higher for high-income
households. - Simple subcultural interpretations are thus not
easy to support there is considerable diversity
in the membership of gun owners. - Research shows little relationship between gun
availability and the number of nonfatal gun
crimes, although greater gun availability was
associated with a higher rate of felony murder. - Gun availability alone cannot explain high rates
of violent crime in the U.S.
11Interventions Disrupting Illegal Markets
- KANSAS CITY GUN EXPERIMENT
- Based on the theory that additional, proactive
police patrols to detect gun violations in
high-crime areas would increase gun seizures and
reduce gun crime either by deterring or
incapacitating gun-using criminals (Sherman,
1995) - Results
- Target Beat Gun seizures by police increased
significantly (by 65), while gun crimes declined
significantly (by 49). - Comparison Beat During the same time period,
there were no significant changes in gun crimes
or guns seized. - Several alternative hypotheses were ruled out
(e.g., only gun crimes were affected by the
directed patrols there was no measurable
displacement of gun crimes to beats surrounding
the target area).
12Interventions The Boston Violence Prevention
Project
- Step 1 Officials analyzed the supply and demand
for guns. - Both victims and offenders typically had
histories of gang membership and high rates of
offending. - Youth homicides were concentrated in
neighborhoods that hosted an estimated 61 gangs
involving about 1,300 juveniles. - Step 2 A stern message was delivered to gang
members. - Continued violence would lead to severe personal
restrictions for those on probation and parole
(bed-checks, room searches, and enforcement of
warrants), intensive police presence in
neighborhoods, search and seizure of unregistered
cars, vigorous arrest and prosecution for
disorder offenses (drinking in public), and
strict enforcement of curfew laws. - Step 3 City, state, and federal representatives
helped establish a large network of
community-based job, recreation, and prevention
programs for juveniles. - RESULTS
- 63 decrease in monthly youth homicides
- 32 decrease in of shots-fired calls to
police - 25 decrease in monthly firearm-related assaults
(Braga et al., 2001) (but no real control group
many strategies)
13Interventions Gun Control Legislation
- Three broad strategies are possible
- Altering Gun Uses or Storage (regulations
affecting the legal carrying, storage, and use of
a firearm) - Reducing Lethality of Guns (e.g., technology such
as user identification mechanisms and trigger
locks) - Market-Based Strategies (i.e., restrictions on
availability)
14- 1. ALTERING GUN USES OR STORAGE (regulations
affecting the legal carrying, storage, and use of
a firearm) - Bartley-Fox Laws in MA expanded gun licensing
procedures, and mandated a 1-year sentence for
unlicensed carrying of a firearm. - During a 2-year evaluation period, the law
decreased gun use in assaults and robberies, and
decreased gun homicides (Pierce Bowers, 1979). - Sentencing enhancements for the use of a gun
during a felony - Study of six jurisdictions showed a decrease in
gun homicides, but no change in non-gun
homicides, and no consistent effect on gun
robberies or assaults.
15- 2. Reducing Lethality of Guns (e.g., technology
such as user identification mechanisms and
trigger locks) - Includes measures that designate certain firearms
(e.g., assault rifles) dangerous because of
concealability, firepower, or other risk - Also includes measures that restrict access to
certain types of weapons or ammunition by law, or
makes weapons less dangerous by requiring
specific types of safety technology (e.g.,
trigger locks) - Little evaluation evidence of these strategies
exists at this time.
16- 3. Market-Based Strategies
- Examples
- Tougher regulation of federal firearm licensees
- Limits on of guns that can be purchased in a
given time period - Gun bans
- Gun buy-backs
- Enforcement of existing laws against illegal gun
buyers or sellers
17- Firearms can be diverted to criminals and
juveniles at any stage of legitimate business. - Examples
- Stolen guns
- Straw purchases
- Lying and buying
- Gun dealer ignores regulations
18Screening Gun Buyers
- Federal Gun Control Act of 1968 prohibited gun
dealers from selling to dangerous categories of
persons (juveniles, convicted felons, drug users,
and former mental patients). - No significant effects on firearms injuries or
deaths were found in an evaluation study
(Zimring, 1975), although weak enforcement of the
laws is partially responsible for weak effects. - The Brady Act (1994) mandated presale background
checks and prohibited retail sales of guns to
persons in high-risk categories specified by
federal law. - Only about 2 of all applicants are rejected
annually. Most rejections (58) were for a prior
felony conviction or a current felony indictment.
- Few evaluations exist (but see Ludwig Cook,
2000), but given the small percentage of
rejections relative to applicants, the cost
effectiveness of this strategy is questionable.
19District of Columbia Handgun Ban (1975)
- Prohibited ownership of handguns by virtually
anyone except police officers, security guards,
and previous gun owners. - During periods of vigorous enforcement in the 3
years following implementation, the law reduced
rates of gun robbery, assault, and homicide. - However, gun homicides increased in 1988 when
crack markets exploded.
20Right-to-Carry Laws
- Some researchers (e.g., Lott) have claimed that
increased handgun availability among the
population provides a deterrent to would-be
criminals. - NRC (2005) It is impossible to draw strong
conclusions from the existing literature on the
causal impact of these laws. - Limitations of Research
- Inadequate controls for cross-jurisdictional
variations in poverty rates, gang and drug
activity, and local and state governmental gun
laws and anticrime programs - Short time series
- Small number of jurisdictions
- Questionable measurement of key variables
- A lack of individual-level data of actual gun
attitudes or use
21Conclusions
- Because felons most frequently obtain their
firearms through unregulated sales, the benefits
of further federal regulation of guns may be
small. - While a diverse array of legislation has been
attempted in recent years, much more rigorous,
controlled evaluations of different interventions
are needed. - Strategies aimed at disrupting illegal markets
and targeting high-risk individuals appear most
promising.
