Ok so your first rates are wrong

Now can you see how, even though blacks are such a tiny minority, the huge numbers of murders they commit, in addition to the decent disparity between black on white vs white on black numbers leads to a vastly higher black on white murder rate than the reverse

It doesn’t seem like you’ve thought his through

What are the total number of black on white murders

Now what are the total numbers of white on black murders

Now put those into per capita figures (by population).

That is how you get a murder rate

You will see that it is far more likely for a black person to kill a white than the reverse. About 8 times higher. Virtually every crime is this disproportionate

Just for fun now do the aggravated assaults by blacks against whites and then the reverse. How bout rapes? This will be good...
