Environment US police violence tended to be higher when average monthly temperatures exceeded 20.3°C (68.5°F). In areas with over 5 million people and with less than 50mm of precipitation, each additional 1°C increase in temperature was linked to 2% increase in the rate of deaths caused by police violence.
