The Globe and Mail has been publishing a fabulous data-driven expose on how the police categorize one out of five sexual assault reports as unfounded. They have a web essay Will police believe you? that summarizes the investigation. There is another article on How The Globe collected and analyzed sexual assault statistics to report on unfounded figures across Canada. While this isn’t big data, it shows the power of data in showing us that there is a problem and prodding police departments to start reviewing their practices.
