> The data is voluntarily submitted by as many as 18,000 law enforcement agencies across the country that participate in the FBI’s Uniform Crime Reporting (UCR) Program. This is an open data project to improve the nation’s crime data and promote transparency in the criminal justice system
My take is yes since it's coming from 'law enforcement agencies' but maybe it's not as comprehensive as it could be since it's 'voluntarily submitted'
Yep. When you view results, it'll tell you what portion of the agencies in that region submitted information so you can get some sense of its comprehensiveness.
