You're assuming that they don't matter equally. That may be true, but it's dangerous to start off by simply assuming the validity of your thesis.
Moreover, it assumes that the way in which they don't matter equally is based only on racial lines. I'm far from convinced that's completely true. It appears that's some of it, but the fact is that police kill lots of innocent whites, hispanics, and asians as well. That being the case, wouldn't it make more sense to look more broadly at where the disparities are, rather than simply assuming that it's all racial while refusing to entertain any other possibility?
