I assumed you were going to use the FBI crime statistics that we all know, but your numbers are way off: https://ucr.fbi.gov/crime-in-the-u.s/2016/crime-in-the-u.s.-2016/tables/expanded-homicide-data-table-3.xls

American whites kill American whites 3 thousand times a year (give or take).

American blacks kill American whites around a couple hundred times a year.

American whites kill American blacks above a hundred times a year.

You don't calculate liklihood from death statistics, but the number of black-on-white murders is twice that of white-on-black murders, not twenty-seven times that. Intra-racial murders are the most common, and are 10 times the number of inter-racial murders.

I'm guessing that the only way you got to those numbers has something to do with a per capita rate.

Murder rates like these can go on for quite some time because the overall crime rate is lower now than it was in previous decades; although the crime rate of specific shithole cities is spiking.

Edit -

Downvoting FBI crime statistics doesn't negate them. You should have figured this one out by now.
