OK
> 2) his data is fed by news reports which may not evenly cover actual incidents
OK, although I doubt white deaths are reported LESS than black deaths (nothing to support it)
> 3) 25% of the data lacks racial info at all
OK, but this won't affect conclusion that much. Even if all those incidents involve black subject, it won't affect the conclusion.
> 4) the likelihood of biased policing being a factor in higher reported African American crime rates completely undercuts the conclusion he reaches

Of the 12,664 murders 4,077 were cases where offender's race was unknown leaving 8,587. Males were responsible for about 90%. 90% of 8,587= 7,728 US murders we know to be committed by males. White males committed 45.2% of 7,728 murders which = 3,143 murders. Black males committed 52.4% of 7,728 murders which = 4,049 murders. Black males make up 7% of this nation's population with about 19m individuals. White males make up about 28% of this nation's population with about 112m individuals.
Odds of a white man being a murderer: 1 in 35,634. Odds of a black man being a murderer: 1 in 4,693.
African American male is 9 times more likely to commit homicide. It's very unlikely that biased policing is the cause of 9x homicide conviction rate.
