It's actually quite easy.
Enforce the race equality that the left is always yapping about.
- no, a white racist cop murdering a black man is not grounds for mass rioting and looting. Whitey doesn't loot and riot when blacks kill whites - so f*** off with your virtue signalling.
- if blacks are equal to whites, then treat them the same. Awhile ago some disgruntled whites got together and started chanting and waving tiki torches around. In the ensuing fracas, some people were hurt and the perps got 15 years in prison. Do the same to the blacks, that are murdering and looting and burning and if they don't like it - fuck them, Africa beckons.
