Police

Many police department web sites post press releases or arrest/incident reports that can be used as the basis for newswriting exercises.

The Smoking Gun - www.thesmokinggun.com - and Court TV - www.courttv.com - both carry arrest reports from high-profile cases, many involving celebrities.

Web sites operated by the Bureau of Justice Statistics - www.ojp.usdoj.gov/bjs/ - and the FBI - www.fbi.gov
- both have a wealth of statistical data on crime in the United States. Users can access press releases or raw numbers broken down into a variety of categories that can be the basis for news stories.
