Don,
"I have not accused you of anything other than drawing a conclusion by ignoring significant evidence to the contrary, which is what you have done, and continue to do."

I am not aware of having ignored any evidence.
Do you mean evidence of the over-representation?
There is no evidence of significant numbers of other groups in this particular crime.
There surely are others involved, but BPs are disproportionately represented.
Do you mean the explanation?
The only evidence for that is the stature of those proposing it, and the absence of an alternative.
No evidence to ignore Don.

"Unless you base your conclusions on the whole culture they simply are invalid."
I have made no conclusions at all about the culture.
I have left that to people familiar with it, or actually part of it Don.
