My family had a post pandemic and going away party.
Hanging out afterwards we started discussing George Floyd's trail and a number of us thought that maybe this was the tipping point.
Then yesterday another young black man was killed by the police. In Minnesota.
So, not a tipping point or at least not the one I wanted.
I assume your viewpoint here is that as long as we keep seeing "black man killed by police" in the news that implies that there are still race problems in America, whether in general, or specifically at the police. (Or do you mean about police killing people in general not specific to race?)
However, there are 200-300 black people killed by police every year in the US.
Sadly, that number is not going to suddenly fall to zero because of what happened to George Floyd.
300-500 white people are killed every year by police. However, when we factor in that there are many more white people, on a per person basis, more black people are killed per head of population.
So, now let's say in the future that the number of black people killed by police falls to 50 people per year while the number of white people increases to 600 per year in the US. This would then mean that black people are being killed at a lower rate than white people even after adjusting for population size. And yet, even if that were to happen, that would mean you would still have "black person shot by police" in the news once a week on average. [Edited and corrected this to change "man" to "person".]
So we can't conclude anything at all about wider issues on race from the fact that we see "black man killed by police" in the news from time to time.
Instead, wait a year or two and look at the overall stats.
