Something like 83-84% of white victims of violent crime were harmed by white people.
Since there are more whites people to be victims of violent crime than there are black people to be this will account for a good chunk of the difference.
Especially when habitual criminals, responsible for why the crime rate in black communities is so bad, are usually going to be lazy opportunists attacking whatever comes their way.
not all of the attackers of those that 83-84% were white caucasian, a percentage of those were white hispanic, they count hispanics as white to bump up white attacker/defender figures, and keep them separate when counting white victims, to reduce the numbers of whites - on purpose.
