If you believe people different from you are being killed due to the fact that you and your race perceive them as ignorant for the way they act then you are telling me you are prejudice. If you think for one second that you can judge a person's intellect by their clothes, their attitude, their actions, then you are truly a fool.
To take this prejudice that people of color are lesser than pale people as the reason they are being shot and murdered by police is pure ignorance. Most of these people being shot are not given a second to react, not given a second to even speak, they are being approached and killed.
If a person dresses, speaks, appears different than you, that does not make them a different class or lesser nor greater than anyone else.
