A non-profit, non-government affiliated project, this free, browsable database of crimes reported in Chicago (with source data from the Chicago Police Department’s Citizen ICAM website), makes use of Google for map views, and RSS feeds “for every block and police beat in the city.” Users may browse by crime type, street, date, police district, location and city map, or use the Search function (which uses “did you mean” functionality to check spelling). The site’s data is refreshed daily, covers a rolling 90 day time period, and is the work of Adrian Holovaty and Wilson Miner.
