It is still going on and will continue as long as the cops keep murdering and profiling black people.
Most of the time, the only time black people get killed by cops is when they get violent. The same is true when white people get killed by them.
The media tends to give a lot of coverage to the unusual cases of nonviolent suspects getting killed by cops, and typically only when it is a black victim and a white cop. That's in order to maximize racial tension.
Police reform is a valid cause, but it has been racialized by opportunists and the media. It's not a racial issue but instead an authority one.
