A few outliers do not determine the overall group. You may have seen many videos of white cops targeting black people. However this does not meant the entire police force of 800, 000 people is racist. Even if 8, 000 police are racist, That is 1% of the police force. Would you make an assumption of an entire group based off 1% of it's members? No, That is absurd.
Obviously the racist and crooked cops should be punished.
