First of all there is a significant correlation between poverty rate and
violent crime. That is well-established.
Secondly, where violent black crime occurs and where violent white crime occurs are dramatically different. Violent black crime occurs in our largest and most densely populated arears which also happens to be our largest media markets as well so it is very well reported on and covered, while violent white crime is more rural, remote, less covered by the daily media, and less likely if for no other reason than population density.
Recently, or relatively recently with the opioid epidemic you've seen those lines blur. If you introduce a widely desired illegal substance into a poor community that cannot afford it then crime and especially violent crime will certainly follow regardless of race as desperate people vie to sell and buy it, certainly.
