Hover over a precinct for the number of complaints in the map.
You can select from years 2014, 2015 or 2016 using the Year filter drop down above the map. You can also select specific months in the Month filter drop down above the map. The default is set to look at "all" months for the selected year.
Number of complaints by type -- force, abuse of authority, discourtesy and offensive language -- can be greater than the total complaint number.
The reason for this is that a complaint categorized as "force" for example, is a case in which there was at least one allegation of force. That case may also contain allegations of discourtesy, abuse of authority or offensive language.
