Unequal race ratios can lead to biased opinions. For instance, the mindset that most black people live in public housing. Black officers will have a better understanding of the struggles and circumstances of common black citizens.
The disrespect and biased opinions can instill fear in the hearts and minds of members of the community. Whenever there is a situation where the police are involved, there is a fear of becoming a statistic on the news because he or she was killed by a cop like Michael Brown and Eric Garner.
