No, they don't. That would entail Police stopping the niggers from attacking each other, which would entail the use of firearms. If that happened then the niggers would scream that raycissss cops were shooting niggers for no reason. Then there would be rioting, bitching and lawsuits.
If niggers want to kill each other, we should let them. Kind of like Ancient Rome. We build a huge arena with bulletproof glass around the audience area and let the niggers shoot and fight it out there. In this arena we could have the Nigger Death Match Challenge and allow them to legally kill each other so long as they did it in the arena. We could sell tickets and put it on pay per view. It would be a real money maker and people from around the world would tune in.
We would take feuding gangs, give them guns and ammo and just set them loose in the arena. The 8th Street Crips vs the Downtown Bloods. Hand them all automatic Uzis and kick back and watch the fun.
