You must be wondering why blacks didn't find this country and import white slaves. Had they done that, we wouldn't have this problem. No, we'd have the opposite problem. Blacks would be complaining about whites and their inner city crime problems. And whites would be complaining about dirty black cops profiling them. 

Are you mystified that crime exists? It seems like you are. Regardless, crime doesn't excuse crime, so just because blacks are committing crime doesn't give police the right to commit crime. I know it's tempting, but don't do it. Do you understand?
