The Wall Street Journal has published a useful statistical breakdown of murder in America for the decade 2000 - 2010. Among the many interesting facts shown is that, while non-Hispanic whites outnumber blacks in the country by slightly less than 5 to 1, black murderers outnumber white murderers by about 7 to 5 (among the population of murderers whose race is known). I point this out not to disparage blacks, but to rebut the constant, and constantly absurd, charge that the disproportionately large number of blacks on death row, and as prisoners serving sentences for homicide, is a result of an endemically racist criminal justice system.
Baloney. It's a result of the fact that blacks commit a grossly disproportionate number of murders.
