Interesting discussion, I looked up some stats. What the FBI and govt. stats say:
US homicide offenders by race, 1980–2017[51]
According to the FBI, African-Americans accounted for 55.9% of all homicide offenders in 2019, with whites 41.1%, and "Other" 3.0% in cases where the race was known.[52] Among homicide victims in 2019 where the race was known, 54.7% were black or African-American, 42.3% were white, and 3.1% were of other races.[53][54]
The per-capita offending rate for African-Americans was roughly six times higher than that of whites, and the victim rate is a similar figure. Most homicides were intraracial; where the perpetrator's race was known, 81% of white victims were killed by whites and 91% of black or African-American victims were killed by African-Americans.[54]
