The mapped icons are based on police reports taken by officers when responding to incidents around the city. The time for an incident to show on the map is 12 hours after the report has been processed. However, the time for a report related to the event to be made available online can take 2-3 business days.
This map provides a good overview of reported activity going on in your neighborhood. The icons for these incidents are based on initial reports, however, and are subject to change as the investigation proceeds. For this reason, the mapped incidents will not match monthly crime statistics and will not provide a true measure of safety or crime in an area.
