Uniform crime reporting program

The FBI Uniform Crime Reporting (UCR) Program produces a great deal of information every year and provides a picture of crime in the United States. Provide an explanation of the UCR and comment on its accuracy, as well as your thoughts on how it could be enhanced. What is the participation like among police departments? What other reports contribute to the UCR? How can reporting be improved so that we have a more realistic picture of crime? What is the dark figure of crime?
