The document discusses symbolic interactionism theory and its application to understanding police brutality against black communities. It explains that police brutality is a form of institutional racism, as policies like the war on drugs have disproportionately targeted and controlled black neighborhoods. Symbolic interactionism looks at how socialization influences people's interactions and behaviors. It suggests that within the context of police-civilian encounters, black people are viewed as "rule violators" by police who see themselves as oppressors, and vice versa. The roles and expectations internalized by police and civilians alike shape their interactions.
