Question

Following widely publicised incidents in cities like Baltimore, Ferguson, and New York City, police departments around the US have been accused of using excessive force in their interactions with the black population. Activists have mentioned the lack of proportional representation of black people among police officers as the main cause of this excessive force. You have obtained a sample of interactions between police officers and members of the public, which includes information on whether police force was used. Suggest an empirical strategy to test whether the use of police force is discriminatory.
