Find non-lethal and excessive force means to de-escalate situations

There have been psychological studies done that people who are not black can assume that a black person is angry or aggressive or even "bad" simply by the way they look and the way we perceive them.

This test can be done with the police force and other authority figures to help them figure out if they are inherently racist. Without judgment, what are the police force and other authority figures doing to learn how not to react to black people and people of color in an instantly suspicious or negative manner?

For example, a police officer might pull over a black person speeding even though he or she was in the midst of many speeding people who might not have been black, indigenous, or people of color. The police officer might have made a different decision if they were trained how not to be racist.
