SavIsa Security has found a very useful website that maps crime statistics not only within Detroit but the surrounding suburbs of Detroit, Michigan known as the Tri-County area and the entire United States of America.  This website is truly awesome and even includes  tools that enable you to change date ranges, crime types, and even  street level views that zoom into satellite imagery.

Each crime type you click on has detailed information about that particular crime.  The only down side that was found is that certain communities are not listed, not sure why.

Click the following link to go check them out Crime Mapping.  Truly a useful website.
