analyzing crime patterns, creating solutions, and evaluating their impact; the same process
employed by Joliet’s Strategic Tactical Deployment program.
Strategic Tactical Deployment
The Joliet Police Department implemented the Strategic Tactical Deployment (STD)
program in 2007. Each week, the Joliet Police Department holds a compstat-like meeting
attended by supervisory and command personnel, during which current crime conditions are
reviewed. Two computer-driven projectors are used to provide information about serious crimes,
identify recent parolees and gang members, and provide other intelligence information. The
presentation is created by the police department’s intelligence analyst and a handout of the
presentation is generally available. The city of Joliet is broken down into three police districts:
East, Central and West. Specific attention is given to gang crimes, gun violence, and drug
activity in each of these areas. This strategy was intended to supplement routine patrol and
provide an offender-specific focus to regular police operations.
During the meeting, Strategic Tactical Deployment areas are chosen for the following week
based upon a spatial and temporal analysis of the data. STD deployments are determined by
reviewing the past thirty day, and hour and day of week, patterns of violent crime. In addition,
kernel density maps (see Figure 1) are created based on the past week’s activity (drug arrests,
gang contact, parole contact, probation contact, robbery, weapon seizures, shots fired, aggravated
discharge, reckless discharge, aggravated battery with a firearm, and homicide). Inputs are
weighted depending upon the severity of the incident and STD areas are chosen for the
upcoming week based upon the as collaborative discussion and the hotspot maps.

STD deployments typically occur on weekends during the evening hours from 9:00 PM until
1:00 AM. Depending on manpower availability, one or two additional patrol units are assigned to
preventative patrol in the STD areas each evening. The STD initiative is a voluntarily overtime
program funded by a grant from the U. S. Bureau of Justice Assistance. The officers are asked to
focus on violent crime and gang activity and are not required to answer routine calls for police
service.
Those attending the STD meetings are also provided an STD Meeting report (Appendix 1),
which is also available electronically to all Joliet police personnel over the department’s
computer system. The report contains detailed information about serious crime in each of Joliet’s
three police districts. The report also contains information about recent arrestees, parolees, and
probationers residing in Joliet. (This information is not included in the appendix of this report for
privacy reasons.)
New STD Activity Summary Reports (Appendix 2) and Field Interview Cards (Appendix 3)
have been created for the STD program in order to accurately gather data for the project’s
evaluation. Officers assigned to STD patrols are also provided with an STD map (Appendix 4)
18
and are required to complete the STD Activity Summary Report, which has been redesigned to
capture the following information: arrests, offense reports taken, compliance tickets issued, field
interview cards written, weapons confiscated, foot patrol activity, traffic stops made, traffic
citations issued, parking citations issued, and vehicles towed.
In addition, the STD Activity Summary Report includes the following STD Guidelines:
Patrol only within the area designated on the map on the back of the report
Field Interview (FI) Cards must be completed on all contacts made
Zero tolerance should be utilized in the targeted areas
Activity is monitored on a weekly basis; those officers who fail to show enforcement activity are
barred from future participation in the program. Although specific officers are assigned to the
STD program, the whole police department is made aware of the STD effort and the STD area
boundaries.
Area-Based Crime Response
On 26 August 2012, the Joliet Police Department changed the name of the Strategic Tactical
Deployment (STD) program to Area-Based Crime (ABC) Response. Joliet announced that the
name was changed in order to expand the program by infusing offender-based strategies into the
already existing place-based program. While Joliet had focused on the exchange of information
with probation and parole from the inception of the program, it was felt that greater
communication was needed between the participating agencies. This new effort would continue
to exchange information as in the past, but with a greater emphasis on working with both
probation and parole to revoke the probation and parole status of violent offenders. In addition,
Joliet announced that the program would now be managed by a committee of supervisory and
command officers and increase its focus utilizing the following four discrete strategies:
19
Better communication with probation and parole
Enhanced data analysis
Expanded intelligence processes to provide additional information to patrol officers
Better focus on hot spot areas including parole sweeps, targeting of known offenders, and
tracking tension between gang members.
To further gain cooperation and buy-in from patrol officers, roll call training sessions were
held. The training was attended by every police officer involved in the STD program and
included a twelve-slide presentation and a question and answer period (Appendix 5). Included in
the training were:
the purpose of the program
the need for accurate and complete field interview and arrest information
the need to maintain strict STD area integrity
Probation Cooperation
An important part of each STD meeting was the exchange of information with the Will
County Adult Probation Department. (Juvenile probation did not participate in this program.) A
probation supervisor is assigned to the STD project and attends each STD meeting. Joliet
maintains a database of all adult probationers, based on updates from Will County Probation.
This database is cross-checked on a daily basis with all police contacts: field interview cards,
arrests, suspect information. All probation contacts were forwarded to Will County Probation
each week prior to the STD meeting in order to allow them to research problem probationers and
respond to questions at the weekly meeting. Table 1 provides a list of the exchanges of
information that occurred during the first eight months of the study.
