title: Version 1

description: The Strategic Approaches to Community Safety Initiative
(SACSI), in Detroit, Michigan, involved a team of federal, state, and
local agencies that worked together to systematically address gun
violence in that city. The purpose of the SACSI project was to examine
the dynamics of gun violence and the manner in which such cases are
processed within the criminal justice system, and to evaluate two
SACSI gun violence interventions in Detroit's Eighth Precinct. The
first intervention, "Operation 8-Ball," was a warrant sweep aimed at
gun-involved offenders with outstanding warrants, who were residing in
the Eighth Precinct. Part 1, SACSI Monthly Gun Robberies Data,
contains the monthly totals for stranger gun robberies in three
Detroit precincts, collected to measure the impact of the "Operation
8-Ball" intensive warrant enforcement program conducted in late
September 2001. Part 1, contains six variables. The second strategy
for addressing gun violence adopted by the working group was a
gun-involved parolee supervision component entitled the Detroit SACSI
Parolee Initiative. Part 2, SACSI Monthly Contact for Parolees Data,
contains the monthly totals for a variety of parole contacts,
collected to measure the intensity of a supervision program
implemented for gun offenders, which commenced in July 2002. Part 2
also contains levels of parole violations in an intensive parole group
in the Eighth Precinct of Detroit. Part 2, contains 16 variables.

description: A task force was created to work together with
the research team in a collaborative process in the problem analysis,
design, and implementation of interventions. While the research
partner was responsible for conducting the data collection and problem
analysis, this work was to be informed and guided by the task
force. Data collection, which was facilitated by the FBI liaison to
the SACSI working group, involved active collaboration among the
Detroit Police Department, Wayne County Community Justice, the
Michigan Department of Corrections, and the Bureau of Alcohol,
Tobacco, Firearms, and Explosives. The research team focused their
analysis and evaluation on two Strategic Approach to Community Safety
Initiative (SACSI) gun violence interventions in Detroit's Eighth
Precinct.
The first intervention, "Operation 8-Ball," was a warrant sweep
aimed at gun-involved offenders with outstanding warrants residing in
the Eighth Precinct. Part 1, SACSI Monthly Gun Robberies Data,
contains the monthly totals for stranger gun robberies in three
Detroit precincts, collected to measure the impact of the "Operation
8-Ball" intensive warrant enforcement program conducted in late
September 2001. One precinct represented the intervention precinct and
two control precincts' monthly robbery totals were used for
comparisons. A total of 60 monthly observations were collected.
Electronic data aggregation of official crime reports were used to
obtain the monthly counts.
The second strategy for addressing gun violence adopted by the
working group was a gun-involved parolee supervision component
entitled the Detroit SACSI Parolee Initiative. Part 2, SACSI Monthly
Contact for Parolees Data, contains the monthly totals for a variety
of parole contacts, collected to measure the intensity of a
supervision program implemented for gun offenders, which commenced in
July 2002. Part 2 also contains levels of parole violations in an
intensive parole group in the Eighth Precinct of Detroit. The parolees
were known gun offenders. A matched control group (age, offense, race,
and gender) was drawn from the larger Detroit catchment. Parallel data
were summarized for match group members. Monthly observations used
intensive and match average levels of contact that were recorded in
official parole records.
description: Part 1, SACSI Monthly Gun Robberies Data,
contains six variables: year, month, and monthly gun robberies
recorded in the Sixth, Eighth, and Tenth Precincts. A variable
labeled, "Operation 8-ball intervention" identified if the data were
collected in the pre- or postwarrant enforcement period.
Part 2, SACSI Monthly Contacts for Parolees Data, contains 16
variables including home contact rate, office contact rate, phone
contact rate, collateral contact rate, the substance abuse violation
rate, and the total violation ratio for both the SACSI intensive
parole group and the matched control group. Other variables capture
the total number of SACSI parolees on caseload for the month, as well
as the total number of match parolees on caseload for the month. Other
variables include the month/year observed and the pre- and
postintensive supervision periods.

description: For Part 1, the monthly totals for stranger gun robberies
in three Detroit precincts were obtained from the Detroit Police
Department for a period of five years from 1999 to 2003, resulting in
60 observations. For Part 2, the monthly totals for a variety of
parole contacts were obtained from the Michigan Department of
Corrections for a period of two years, from 2002 to 2003, resulting in
aggregate official parole contact data (by month and year). In Part 2,
case load fluctuations yielded variations in the total number of
underlying parolees observed and there is not perfect correspondence
between the two groups.
