This is the only way to measure whether the policies and programs that we have in place now are effective or not. That's basically what data collection does. It measures how frequently, if at all, racial profiling happens, and what form it takes. Does it mean that more people of color are getting stopped? Or more frequently stopped? Or once they're stopped, they're getting searched more frequently than a white person would get searched?
