Dashboard Walkthrough

The Use of Force Report is an interactive data visualization summarizing most use of force Incidents by Portland Police Bureau members. This tool is built to provide custom analyses of use of force data to interested members of the community.

The report will be updated 45 days following the end of each quarter.

The horizontal lines with circles, resembling an abacus, provides tips for using the interactive dashboard functionality.

e. Toolbar

The toolbar, located at the bottom of the visualization, contains several buttons that assist in the analysis of the data.

The “Undo” and “Redo” buttons become active when the above filters are applied to the report. They operate just like the Undo and Redo buttons in other programs such as Microsoft Word.

The “Reset” button reverts all filters back to their original setting when you first visited the page. This is a great way to start with a “clean slate” after clicking several filters.

Tableau is the name of the software used to create this report visualization.

The “Download” button allows users to save a static version of the visualization. This option is great for printing out copies of the map to share at meetings or to include in a presentation.

“Get the App” takes you to a download page to acquire a Free Trial of Tableau Desktop.  This is not necessary, or recommended, to fully analyze and view the report.

“Tableau Workbook” allows you to download a file that works with the full version of Tableau Desktop, mentioned above. This is not necessary or recommended.

“PDF” allows users to export the report, with all of the filters you set, as a PDF. The options dialogue allows custom scaling and paper size options. When choosing to export as PDF, make sure to keep the layout as portrait and content as “this dashboard.”

The "Crosstab" and "Data" options are unavailable for use on the workbook's main page.

“Image” creates a .png file of the report with all of the selected filters.

4. Dashboard Walkthrough

The Force Audit Report contains 5 interactive dashboards (and an accompanying definitions sheet) that provide multiple analyses and presentations on use of force subjects and incidents. Each tab of the visualization presents the data in a slightly different way, depending on the focus of interest.

I. Executive Summary

The Executive Summary provides a quick overview of the basic facts and statistics on use of force incidents from Portland Police Bureau members. Hover your mouse cursor over the "Definitions and Additional Info" icons provide detail on the definitions, methodology and caution for use of force data.

II. Subject & Application of Force Summary

The report's second dashboard (titled "Demographics" on the tab) provides basic information on the subjects involved in force incidents and the type of force used.

The "Subject of Uses of Force Table" is a distinct count of subjects against whom force was used. For example, if two officers applied force to one subject, that subject is only counted once in the table.

The "Applications of Force Table" is a count of the total applications of force used by all officers for the designated reporting period. For example, if two officers applied one force application to one subject, there would be a total of two force applications described in the table.

III. Dispatch Call Types & Precinct Breakdown

The "Top Initial Dispatch Call Types, by Case, Resulting in Force" bar chart lists the Top 13 Call Types where force was applied during the incident. The call type is defined by Bureau of Emergency Communications dispatchers and call takers when dispatching officers to the incident. The call types are sorted by the unique count of cases where force is applied, with the dark color in the stacked bar chart signaling Category 2 and 3 force events with the lighter color signaling Category 4 force events.

The "FDCRs by precinct and Month" chart is a total count of all Force Data Collection Reports (FDCRs) submitted in each month within the reporting timeframe. The precinct signifies the officer's precinct assignment and does not necessarily indicate the location of the force incident.

IV. Time of Day & Subject Age Group Summaries

The report's fourth dashboard provides an overview of when force incidents are occurring and additional information on the subjects of force incidents.

The "Uses of Force by Day and Time of the Application" chart is a heat map of the weekday and time of day that force was applied, as reported by officers on completed FCDRs. All times are reported on the 24-hour clock, with all "P.M." times occurring after 12:00 hours.

The "Unique Subjects of Force by Age" bar chart is distinct count of subjects against whom force was used, aggregated by age. Age range categories are defined by the National Incident Based Reporting System (NIBRS).

V. Force Type Breakdown

The "Force Type by Demographics" heap map is a count of each unique force type used on each subject for each incident, by the combined sex / race of the subject. Use scroll bar on the bottom of the chart to view additional sex / race groupings.

Example 1: If three separate officers applied a "takedown" on the same white male subject in the same incident, it is only counted once in the table.

Example 2: Three officers are involved in a use of force incident with a Hispanic Female. Two officers apply a "vehicle ram", while the other officer applies a "PIT". In the table, one "vehicle ram" will be counted for Hispanic Female and one "PIT" will also be counted for the Hispanic Female.

The "Force Type by Armed Subject Weapon Type" is a count of each unique force type used on each armed subject, by the type of weapon possessed by the subject. If the subject was in possession of more than one weapon, they are counted once for each weapon.

Example 3: A subject armed with "Needle / Bodily Fluids" and a "Knife / Edged Weapon / Stabbing Instrument" is the subjected to a "takedown" by one officer. The incident is counted in both the "Needle / Bodily Fluids" column and "Knife / Edged Weapon / Stabbing Instrument" column.
