Why is there so much anger in the Black Community toward law enforcement? What is the root cause of this anger? Is it justified?

Key Points:

Most Americans have high confidence in police, except for black Americans. With a 1.5 percentage point margin of error, 56 percent of black Americans said they had a great deal or fair amount of confidence in police, compared to the 78 percent of white Americans who said the same.
Monmouth’s study found the majority of black Americans — 87 percent — believe that police are more likely to use excessive force against black people, a sentiment white Americans agreed with, though not by an overwhelming margin; 49 percent of white Americans said police were more likely to use excessive force against black people, while 39 percent felt the use of force wasn’t tied to race.
