I guess it depends. If lethal crime was a virus with a 10% kill rate and you had a vaccine that had a 1% kill rate for most of the population, would you mandate it's use?
(that's not really the scenario here and there are a lot of moving parts and racial imbalances, but I'm just trying to wrap my head around things and the question myself, I'm not sure I have the answer even to the one that I just posed)
I guess the answer is you go with what you have, and you try really, really hard to improve that vaccine in the meantime, but it would be an ugly scenario if either the vaccine or the virus behaved differently in different ethnic groups, which seems to be the one that we are in.
Both racism and violence seem to be 'contagious' in some sense in the human population. Some consideration has been given to treating them with the same methods you would use against a viral agent.

Broadly, from a Christian perspective, I suspect that sin is contagious - it almost always invites others in as part of it's effort to justify itself, and both those things fall into that category.
So here's what I think.
Nothing is perfect, and 1% isn't great. But it isn't *static* either.
You will never get it to 0%, but you can try.
And you HAVE to try. And you really have to try hard, and you have to keep trying no matter how low you get it. And when you see it, you have to in effect do some Contact Tracing.
Because if you don't, whenever and
where ever you drop your guard (that "where ever" actually is
really really important, following the contagion model, which I believe to be correct, or at least correct enough to do some good), that 1% will do this:
1.01
1.111
1.2221
1.34431
1.478741
1.626615
1.789277
1.968204
2.165025
2.381527
2.61968
2.881648
3.169813
3.486794
And that's basically how society falls.
