This is probably one of the only studies I've ever seen where they lump Whites and Hispanics in the same category, which completely skews the White number to make it look comparable to the Black ones.  That was clearly an attempt to reinforce white guilt, because if you look at the statistics for murder in NYC, Hispanics are 34.8% and Whites are 8.7%.  The need to twist the numbers to fit a political agenda here is completely obvious.
