Re: Community Police review Board Annual Community Forum
The Iowa City Community Police Review Board (CPRB) held the annual Community Forum on Monday,
April 29, 2019 at 6:00p.m. Board members at the forum were Chair Donald King, Orville Townsend,
Monique Galpin (Vice Chair), David Selmer, and Latisha McDaniel. Staff present were; Legal Counsel
Patrick Ford, Staff Chris Olney and Kellie Fruehling. Guest speakers were Iowa City Police Chief Jody
Matherly and Captain Denise Brotherton.
The forum opened with roll call and an introduction of board members. Chair Donald King read a brief
summary of the board's duties and responsibilities. It was pointed out that brochures on the board's
responsibility and how to file a complaint were on the table in the back of the room. The Chair then
introduced Chief Matherly.
Chief Matherly talked about the accreditation of the department done on a yearly basis and what it
takes to get and keep that accreditation. The department received 2 grants in 2018 totaling
$750,000.00, one for 2 years from the International Association of Chiefs of Police to study
sexual/gender bias in investigations. This should help officers with victim based approach to the
investigation. The other grant was for Data Driven Justice Initiative (DDJ). This initiative looks at repeat
offenders and how to break that cycle. Crisis Intervention Training for officers to do a better job to get
to root of problem instead of just keep locking people up. The Chief also talked about the crime statics
going down. Chief Matherly also set out the new mission statement for the department:
"To work in partnership with the community, enhance trust, protect with courage and compassion,
empower victims of crime through excellence in service"
Chief Matherly then introduced Captain Denise Brotherton, who is in charge of Support Services.
Support Services is everything non police related, but also the community outreach division. Capt.
Brotherton explained some of the department divisions that fall under her command, stressing the
community outreach division officers that should be seen more often out in the community as the
weather gets better. Capt. Brotherton had brochures that were printed in several languages, to help the
immigrant community with questions they may have in regards to the department and community.
The Chair then opened the forum to the public. The following appeared:
Caroline Dieterle wanted to show her appreciation to Chief Matherly for his work with the department.
She also discussed the deer population crisis with the city and DNR.
Ann Marie Drop asked about the DDJ Grants when received and when up. Rec'd 2018 and up 12/2019
DDJ funded one officer (Officer David Schwindt) compiles and sorts the data received.
Orville Townsend asked about police arrests during the football season. (7 last season)
Jeff Falk discussed the school board's recent meeting about school resource officers and what the cost
associated with that would be and more complaints to the Community Police Review Board. Chief
Matherly stats showed 2017 had 81 visits and 2018 had 223 visits to the schools for various reasons. He
said that the school administration, parents and teachers should decide what is best for the schools.
At the conclusion of the public discussion, the Chair thanked everyone for coming and for their input
and stated that there were information packets on the table in the back.
The forum was adjourned at 6:44p.m.

COMMUNITY POLICE REVIEW BOARD
GENERAL RESPONSIBILITIES
Established in 1997, by ordinance #97-3792, the Iowa City Police Citizens Review Board formerly
known as Citizens Police Review Board and now known as Community Police Review Board
(hereafter referred as the CPRB), consists of five members appointed by the City Council. The CPRB
has its own outside legal counsel.
The Board was established to review investigations into claims of police misconduct, and to assist the
Police Chief, the City Manager, and the City Council in evaluating the overall performance of the
Police Department by reviewing the Police Department's investigations into complaints. The Board is
also required to maintain a central registry of complaints and to provide an annual report setting forth
the numbers, types, and disposition of complaints of police misconduct. The Board shall hold at least
one community forum each year for the purpose of hearing citizens' views on the policies, practices
and procedures of the Iowa City Police Department. To achieve these purposes, the Board complies
with Chapter 8 of the Iowa City Code and the Board's By -Laws and Standard Operating Procedures
and Guidelines.
ACTIVITIES AND ACCOMPLISHMENTS FOR FISCAL YEAR 2019
Meetings
The CPRB tentatively holds monthly meetings on the second Tuesday and special meetings as
necessary. During FY19 the Board held twelve meetings and one Community Forum.
ICPD Policies/Procedures/Practices Reviewed By CPRB
The ICPD regularly provided the Board with monthly Use of Force Reports, Internal Investigation
Logs, Demographic Reports and various Training Bulletins. The Department also provided various
General Orders for the Board's review and comment. A senior member of the Police Department
routinely attended the open portion of the CPRB meetings, and was available for any questions Board
members had regarding these reports.
Presentations
In April of 2019 the Board held its eleventh Community Forum as required by the City Charter. Board
members were introduced and a summary given of the boards duties. Chair King then introduced
Police Chief Matherly.
Chief Matherly presented an overview of the police department and spoke about the departments
excellence in service mission. Captain Denise Brotherton gave a summary of the responsibilities of
the Police Department Support Services Division. She spoke about how the police department is
actively pursuing many avenues to reach out to the public through events, brochures, school visits
and overall being assessable to everyone in the Community
The forum was then opened to the public for questions. There were three members of the public that
spoke at the forum. Topics included appreciation to the Chief, deer management issues, concerns
regarding School safety and training of Officers, Data Driven Justice Initiative (DDJ Grant).
Board members spoke briefly about the complaint process and available informational pamphlets.

Complaint Resolutions
The Police Department investigates complaints to the CPRB of misconduct by police officers. The
Police Chief summarizes the results of these investigations and indicates in a report (the Chief's
Report) to the CPRB whether allegations are sustained or not sustained. (If complaints are made
against the Chief, the City Manager conducts the investigation and prepares and submits the reports.)
The Board reviews both the citizens' complaint and the Chief's Report and decides whether its
conclusions about the allegations should be sustained or not sustained. The Board prepares a report
which is submitted to the City Council.
Of the three allegations listed in the two complaints for which the Board reported, none were
sustained.
The Board did not make any comments and/or recommendations for improvement in police policy,
procedures, or conduct.
Name -Clearing Hearings
The ordinance requires that the Board not issue a report critical of the conduct of a sworn officer until
after a name -clearing hearing has been held. During this fiscal period, the Board scheduled no name -
clearing hearing.
Complaint Histories of Officers
City ordinance requires that the annual report of the CPRB must not include the names of
complainants or officers involved in unsustained complaints and must be in a form that protects the
confidentiality of information about all parties. In the two complaints covered by the FY19 annual
report a total of two officers were involved with allegations against them.
ICPD Internal Investigations Logs
The Board reviewed the quarterly ICPD Internal Investigations Log, provided by the Chief of Police.

Iowa City Police Traffic Study
Brief Summary
Prepared by:
Chris Barnum
St. Ambrose University
June, 2019
Iowa City Police Traffic Study
For several years now, the City of Iowa City has partnered with St. Ambrose University
to develop and implement an analysis of the Iowa City Police Department's traffic stop activity,
The current investigation focuses on evaluating stops made by the ICPD between January 1 st,
2018 and December 31 st 2018. These analyses center on evaluating two broad categories of
discretionary police conduct: (i) racial disparity in vehicle stops —instantiated as racial
differences in the likelihood of being stopped by the ICPD and (ii) dissimilarities across racial
demographics in the outcome or disposition of a stop.
To evaluate the racial demographics of stops, our research team utilized driver -population
benchmarks fashioned from roadside observations and census data. A benchmark should be
thought of as the proportion of minority drivers on the roads in a given location. In plain tern7s,
the benchmark is a standard that can be used to judge the percentage of minority drivers that
should be stopped by the police when no bias is occurring. hi Iowa City, the population
characteristics of the city were divided up into one -square -mile units called observation ones'
(see figure one below).

Once the boundaries of the observation zones were determined, roadside surveyors were
deployed to monitored traffic at several locales within selected zones. The observers watched
traffic at various times of the day ranging from 7:00 am until 2:00 am. To date, observers have
logged more than 110,000 observations from locations across the city. Results show a high
degree of inter -rater consistency between observers across all zones. The observational
benchmarks were updated 2018 with additional observations in several zones.
The process of comparing police data to benchmarks is straight forward. it centers on
identifying differences between the demographic percentages from ICPD traffic stop data and
benchmark information. Any positive difference between benchmark values and police data
signifies disproportionality or an over representation of minority drivers in the data. Although,
disproportionality can indicate bias or discrimination, it does not necessarily do so. It is possible
for disproportionality to occur for a number of legitimate reasons, including differences between
racial groups in driving behavior, vehicle condition, drivers' license status and so forth.
Our methodology makes it possible to track disproportionality by area, by time of day, by
duty assignment and by individual officer. While this method serves as a useful tool in assessing
disproportionality, please keep in mind that the method is only an estimate of disproportionality
in police activity, not a certainty. This stems from the fact that the analyses are predicated on
differences between stops and benchmarks, and that benchmarks are formed from samples of the
drivers on the roads in a given area and time. Consequently, like any sample, a benchmark may
be associated with a degree of sampling error.

2018 Analyses
Figures 2, 3 and 4 give the number of 2018 ICPD traffic stops by observation zone for the
department as a whole, as well as for daytime and nighttime patrol assignments. The information
indicates that for each souping, most ICPD officers tended to make the lion's share of traffic
stops in the downtown area of the city (zone 21) followed by the Broadway-Wetherby (zone 29)
and surrounding areas (zones 28, 30 and 13).

Disproportionality
The figures below show the percentage of minority drivers stopped by ICPD officers and
corresponding benchmark values for select observation zones. The charts show information for
department as a whole, as well as the day and night shifts. In each chart, any positive difference
between the percentage of minority drivers stopped and benchmark values signifies
disproportionality. In general, the information suggests that levels of disproportion ality tended
to be lowest in areas where the most stops were made, and highest in areas were the fewest stops
were made.

The index values shown in each chart give a weighted average of the difference between stop
percentages and benchmark values. The higher the index the greater the disproportionality.
Officer Level Analysis:
We calculated a disparity index for each officer making more than twenty-four stops
during 2018. The index consists of two ratios and was calculated by comparing the percentage of
minority stops to minority benchmarks divided by the percentage of whites stops to white
benchmark values. A disparity index value equaling 1.00 indicates no disproportionality in stops,
while values greater than 1.00 suggest disparity. The disparity index values can be interpreted as
a comparison of fractions or ratios. Accordingly, an officer's disparity index value equaling 2.0
indicates that the officer was twice as likely to stop a minority driver as a non -minority driver,
given the benchmark values. And other values can be interpreted similarly. Below we show two
figures, one for 2018 and a second for 2017. In each, the blue horizontal lines indicate 100 stops,
the thick dashed lines show the median index values for the department and the thin dashed lines
give the 9011' percentile index value for the department. The blue or black dots represent officers.

Index
A comparison of the charts suggests that extreme index values for officers decreased in
2018. Although median index values were roughly the same between years, in 2018 no officer
making at least 100 stops, had an index value greater than four, in contrast to 2017 where an
officer had an index value of nearly six.
Stop Outcomes Results
We used an examination of stop outcomes to assess disproportionality in citations,
warnings, arrests, consent searches and probable cause searches. As the name implies, a stop
outcome gives information about the consequence or disposition of a stop. A good example is
whether or not a driver received a ticket as a result of the stop. In what follows, we measure
disproportionality using an estimator called an odds ratio. This estimator is a measure of effect
size and association. It is useful when comparing two distinct groups and it summarizes the odds
of something happening to one group to the odds of it happening to another group.
The values shown in table 1 give odds ratios for various stop outcomes over time. The
information for 2018 shows ICPD officers were: (i) not more likely to issue a citation to minority
drivers than others; (ii) but, were more likely to arrest minority drivers than others; and (in) were
more likely to initiate probable cause searches for minority drivers compared to others. Looking
more closely at arrests, supplemental analyses indicate that the odds favoring minority driver
arrests decreased in circumstances where officers made highly discretionary arrests. In these
situations, officers have a great deal of choice about whether or not to make an arrest. Although
high discretionary arrests occurred rarely (only 74 happened in 2018), when they did occur, the
odds favoring minority arrests fell to 1.38 from 2.04 for non -discretionary arrests. This is an
important finding which suggests officers' arrest patterns are less disparate against minority
drivers in conditions where they have a great deal of choice or discretion.

In 2018 ICPD officers initiated only a single consent search. Consequently, we could not
calculate odds ratios for this outcome. Also, please note that in 2018 we began analyzing the
number of probable cause searches conducted by ICPD, officers. Results from the analyses show
disproportionality. Of the 272 pe searches performed by ICPD officers in 2018, 119 involved
minority drivers. The odds ratio for this information equals 2.45. It is important to note that hit
rates or seizures resulting from pc searches of minority drivers actually occurred less frequently
than seizures involving nonminority drivers. In simple terms, when officers conducted a pc
search, they were more likely to find contraband or evidence from nonnumority drivers than from
minority drivers.
Conclusions
This study examined the traffic stop behavior of the Iowa City Police Department using traffic
stop data from 2018, roughly 12,000 stops. The investigation focused on two broad categories of
discretionary police conduct: (i) racial disparity in vehicle stops and (ii) disparity in the outcome
or disposition of a stop. Findings from the examination of disproportionality in vehicle stops
show stable or decreasing levels of disproportionality for stops made in 2018 compared to
previous years. Additionally, the results of the analyses for stop outcomes indicate some racial
disproportionality in certain outcomes -including moderate amounts in arrests and probable
cause searches.

A Results suggest a degree of racial disproportionality in traffic stops conducted by
the ICPD. A ballpark estimate of the level of disproportionality indicates that
minority drivers were stopped on average about eight percentage points higher
than the observation benchmark values.
Comparatively little traffic stop disproportionality was found in areas of town
where the lion's share of traffic stops were made. Most disproportionality
occurred in areas where stops were less frequent.
s Individual officer analyses show that one individual officers' disparity index values
were considerably higher than other officers' values.
SUMMARY
Disproportionality inmost stop outcomes decreased in recent years. The single
exception was citations, where disproportionality increased. It should be noted
however, that odds -ratio values for citations were comparatively modest.
y During 2016, disproportionality in arrests decreased.
In recent years, officers were about twice as likely to request a voluntary search
from a minority driver as from other drivers. This occurred even though seizures
or hit rates resulting from voluntary searches was about the same for minority
and non -minority drivers.
• Overall, results suggest that the levels of disproportionality in stops and outcomes
is trending lower.

9.h. Community Police Review Board: Proposed amendment to Ordinance &
By -Laws
Throgmorton: Could I have a motion to adopt the consent calendar as presented or amended,
minus Item 9.11., which we will treat, uh, separately.
Cole: So moved.
Teague: Second.
Tluogmorton: Moved by Cole, seconded by .... Teague. Uh, this is, uh, a voice vote? Yeah, all in
favor say aye. Opposed. Motion carries. Okay, moving to Item 9.h. Item 9.h.,
uh, is (clears throat) actually a piece of correspondence concerning Community
Police Review Board's recommendation that we amend, uh, their....the ordinance,
uh.... uh, for the Conununity Police Review Board and its bylaws. Could I have a
motion to approve, to accept, that particular piece of correspondence?
Cole: So moved.
Thomas: Second.
Throgmorton: Moved by Cole, seconded by Thomas. Discussion? Orville, did you want to
address us on this? Orville, maybe for the benefit of the audience you could
elaborate just a little bit about, uh, what's being recommended by the board.
Townsend: Okay. Yeah, Orville Townsend, uh, Whiting Avenue. Um, the board is
recommending that the ordinance be, uh, establish a change that would appoint a
liaison from the City Council to the Community Police Review Board. Uh,
history behind that is, uh, when I first got on the board, uh, and... and the Police
Review Board, we review any complaint that a citizen has concerning their feelin'
that they were treated unfairly by the Police Department. Uh, as you know, the
Police Department, the cars and the officers have video tapes. So any complaint,
you know, all members of the board as well as the Police Chief, you know,
reviews those tapes to see exactly what happened. Uh, when I first got on the
board, um, I was concerned about, you know, a couple situations. Uh, we had a
couple older members on the board whose, uh, feelings and mentality was that,
uh, we have to look out for our boys in blue. And that feeling, you know, I think

Page 6
in some situations they made rulings that were in favor of the officer, but maybe it
should have been otherwise. Situation like this, uh... the citizen's rights are bein'
violated and they're not bein' given the due justice that they should receive. I
found myself in an awkward situation. My choices were 1 could come before you,
the City Council, and I could complain, but 1 didn't think it was appropriate or
productive to wash our dirty laundry in public. If I were to do that, the next day
every paper in the state would have it and it would just be a mess. So I chose not
to do that. I'm the kind of person if there's a problem I feel that we need to work
in the system to fix it. So this is my attempt to do that at this time. I bring it to
you. Uh, the .... I shared my concerns with the board, and as a result of that we are
makin' this reconnnendation to you to appoint a liaison to the ... the Police Review
Board. Now I can hold my own, but in those meetings, when I was, you know,
tryin' to express my concerns, the vote was against me, but not .... not everybody,
you know, we've got a lot of citizens that they. —they get on committees because
they wanna do a good job and they basically wanna make a difference. But they
don't need a hassle. They may not feel comfortable comin' before you, and in
some cases they may not feel comfortable, you know, workin' with the members
on the, uh, board. So what they would do is they would just kinda bury their head
in the sand and we have a problem that, you know, is ongoin'. Also I think it's
important that we acknowledge a reality. You as a Council, you appoint members
to the boards. You appointed me to the Police Citizen Review Board. And I
guess my feelin' is that if there's a problem, you cannot correct it if you do not
know it exists. So our reconnnendation is that, you know .... a liaison will be
appointed to the Police Connnunity Review Board. If there's an individual who
basically doesn't feel comfortable comin' before you or in some cases even
discussin' it further in the, uh, board meetings, then we have a liaison. Now, we
know you guys don't wanna start appointin' liaisons because you open Pandora's
boa:. But 1 think this is an exception. You appoint this board, and if there .... and
this is not just your average board. We're talkin' about citizens' rights bein'
violated. I think that should put this in a category that has more significance. So,
you know, we are submitting this, uh, to you and I would appeal to you to, uh,
give it really heavy consideration and pass this.
Throginorton: Great! Thank you, Orville. Appreciate you comin'! So the question to us really
is pretty simple. It ... we're not gonna vote up or down on this proposed ordinance.
The question is, do we want to have ... uh, put on a formal meeting agenda the
proposed ordinance, which we would then open to public conversation, have our
own discussion, and vote about whether we want to approve it or amend it. So,
that's the question before us. So, and I need to know whether a majority of us
This represents only a reasonably accurate transcription of the Iowa City City Council

Page 7
wants to ... uh, have such a ord... draft ordinance presented to us at a forthcoming
formal meeting. So .... what do you folks think-?
Teague: I would say yes.
Cole: I'm supportive of it. Yes.
Thomas: 1 would say yes as well.
Throgmorton: I would too, as an act of respect to the board. I....1 think there may be particular
aspects of the proposed ordinance that we would want to deliberate upon more
thoroughly.....uh, and I can't predict how that would go .... .but I think as an act of
respect we should do that. Yeah, okay so, could 1 have a motion.... well, we
don't .... we don't really need to have a motion to direct the staff to put it on a
future meeting. Okay, but we want you to do that (laughs) Okay, so.....could I
have a motion to accept the .... the.....do we? (both talking)
Mims: ....motion to accept it (both talking)
Throgmorton: Okay, right. Thank you. So, uh, all in favor of accepting this correspondence
please say aye. Opposed. Motion carves.
