One of the great things about being a law librarian is discovering new and useful information.  Recently, while researching some criminal law and procedure issues, I came across the FBI’s Uniform Crime Reports.  The UCR has all kinds of different annual statistics on crimes and arrests nationally, as well as by region, state and local agency.  You can even build tables of your own with the UCR Data Tool.  If you’re doing any type of statistical research or need crime or arrests numbers, the Uniform Crime Reports is a great place to go.  These Reports and the Bureau of Justice Statistics’ National Crime Vicitimization Surveys are considered the nation’s two crime measures.
