Crime Reporting Geolocation Website
For conducting background due diligence or doing security surveys this tool might be very useful. The website is called Crime Reports and it is a geolocation service that plots police incident reports on a map.
I stumbled upon it through the Ottawa Police Services website, which identifies a number of disclaimers about the accuracy and timing of the data. Users should read and understand the limits of the tool before using it. Obviously coverage in each jurisdiction will vary.
