Stanford University just delivered further proof that massive, readily available data sets can solve tricky law enforcement problems. School researchers combing through a mix of 28,119 Oakland Police Department stop reports, officer body camera footage and community surveys have learned that there are "significant" racial biases at play. OPD officers are not only more likely to stop a black person, but far more likely to conduct searches of black people, even though they weren't any more likely to find something incriminating. Officers more frequently handcuffed black people without arresting them, too. And the pattern is the same regardless of the crime rate in a given region.
