56% of Black violent crime is committed against Whites
2.6% of White violent crime is against Blacks
Fun with statistics:
This means that 100 - 2.6 = 97.4% of White violent crime is done against non-Blacks. OP seems to want us to focus on only Blacks&Whites, so we'll have to assume that "non-Black" means White.
That means that 97.4% of violent Whites do crimes against Whites, as opposed to 56% of violent Blacks.

WOAH! This means that Whites are more dangerous for Whites than Blacks are!
Stay away from me, white boy!
