I haven’t seen what you’ve seen, so I’m not going to deny your experience/impression, but my opinion is that the only case where the races of those involved in a crime matter are when the crime is racially motivated. And that’s the standard I’ve seen major media adhere to, but obviously there’s grey areas.
If you want every crime tallied up against the race of the perpetrator, I’ve got bad news for you; that’s what the kids are talking about when they take to the streets against good ol’ racism, my friend.
