I think the ball is still in both courts, to use a term from the redditor above. The system still has a bit of work to do, but also so do black communities, and you can't deny that.

For example, OP says

"Will it stop police departments from pulling over disproportionate amounts of black people for petty traffic offenses in order to look for drugs, even though studies have shown white people proportionately possess more drugs in cars than black people? No. Will it stop juries and judges from dolling out unfair punishments between black and white people for the same exact crimes? No. Will it cause landlords and credit/banking industries from subconsciously discriminating against people with "black" names? No."

The reason why people make these associations can be from either side. On one hand, the police officer/judge/landlord may have been raised to adopt the idea that blacks are criminals. On the other hand, he may have been someone who has no tendency to dislike someone on account of their skin color, but he has been a police officer in a crime ridden black neighborhood for 20 years, and whether consciously or not, his mind associates a car full of black people with a high potential for criminal behavior.

It is on both sides. There was a video after the Ferguson riots that was trending on reddit, and in it, a black youtuber asked all of his fellow black community members to ask themselves why they thought it was that black people are associated with crime, and made the point that if black people as a whole moved away from that, perceptions would naturally change.

At the same time, this is a group of people only a generation removed from the Civil Rights movement. There is a lot of leftover from that era, especially in the South. So white people cannot step back and hold their hands up as if there is nothing else to do. It's an ongoing process.
