Answer:
Cultural bias
Step-by-step explanation:
Certain verifiable studies have been made across the United States of America on traffic stops, which revealed significant cases of cultural/racial bias. Black people were 20 percent more likely to be stopped and searched by the police than white people.
Within a six-year period, starting from 2011, researchers studied over 100 million traffic stops cases which were carried out by twenty-one state patrol agencies.
