Okay, if all black people are criminals, what do we do? What's the solution?
Unfortunately if you want the West to remain a first world then first and foremost there can't be too many of them in Western Countries. You will barely find any blacks in Asia or Japan. That's a fact.
I would say sterilization and contraception is one way. Another effective method would be to stop the welfare system in the USA and Europe. It has taught neeguls to game the system and have kids just so they can get support from the system. When in a real world governed by nature they would not be able to support all these offspring.
Encouraging the immigration of blacks to Africa is another solution.
Fact is the West as we know it will be a bona fide Third World if their numbers increase.
