> The GAO report also says the Justice Department has largely ignored a requirement included in the 1994 crime bill to “acquire data about the use of excessive force by law enforcement officers” and “shall publish an annual summary of the data acquired.”
Maybe I'm reading this wrong but I read this as "the collection is required by the crime bill passed in 1994". Even if it's not, the FBI surely has carrots and sticks they can use to force participation.
