I actually saw statistics on criminal sentencing with respect to the race of the victim and perpetrator (specifically black and white), which is a pretty good indicator of the perceived severity. Highest sentences went to black perpetrators against white victims; second highest was white perpetrators against black victim.
So the numbers do seem confirm that overall inter-racial crime is more severely punished than the intra-racial kind. It may be likely that the same bias is present in arrest and prosecution rates.
The same statistics show that black-on-black crime is also the majority of crime where blacks are the perpetrators, meaning black-on-white crime is a relative rarity, which might be something relevant.
In fact most black-on-black crime is gang-related, relatively “routine” stuff insofar as this kind of stuff can ever be routine. Shootings over turf wars, etc. Relatively rarer black-on-white crime tends to be more gruesome: kidnappings/rapes and killings, muggings gone worse, the occasional week-long torture fest, etc. In other words, they are not typically crimes committed against/between hardened criminals, but against ordinary and innocent people.
Final fun fact: race/crime stats are one of the go-to classes of examples stats professors use for how stats data can be manipulated improperly to paint one picture. In fact death sentence by race of victim and perpetrator is a classic example of what’s called Simpson’s paradox, by which conditional probabilities paint a picture not only different but
completely the opposite of marginal probabilities. Put another way, when looking specifically at the race of the victims, black criminals are more likely to be executed than white criminals for both black victims and for white victims; but when you erase the distinction between victims, white murderers are more likely to be executed. Why? Because the murderers of white victims are more likely to be executed than the murderers of black victims, and white victims are more likely to have been murdered by white murderers, and this association is obscured when looking at conditional probabilities.
Full disclosure, I’m a statistician by trade.
I fear that with this ruling that our society may soon become infested with gunslinging punks who only need to say that their killing someone was in self defense to become exonerated. For example, “but I saw him reach into his waistband.”
You get that you can die from having your slammed repeatedly into concrete, right?
