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.
