As my employer was developing more communication channels, particularly between management and wage earns in both factory and office, our human resources VP commented:  "The more you communicate, the more likely that you will  be told you're not communicating enough."   Raised expectations after recognizing the need.

Expectations of race equality have been raised.

Black issues are not the same now as they were in the late 50's.   That doesn't mean that racism has disappeared.  Black American's still face daily prejudice in all social/economic strata. 

I suspect that black citizens see the conflict primarily as race identity and discrimination in enforcing civil law.   Other's might feel it is a battle of authority(power) and individual freedoms.   Other's view it as a very unsafe community  leading to ultra defensive actions taken by police in support of civil law.

My guess is that all these views are very real and all are probably true some share of the time.
