Police violence is not uncommon in America, and the risk of civilians’ being killed by police is considerably higher here than in similar countries, making it a major public health issue. For Black Americans the risk is significantly higher. In this study, we analyze the political determinants of police killings of Black Americans, with a specific focus on corruption in American states. Our evidence suggests that police can kill Black Americans with impunity because of a lack of accountability – exemplified by corruption – that is largely determined by political influences. Our findings point to ways in which the responsibility for police violence and killings is deeply rooted and influenced by the values of the wider society.
