In 2018, there were 258 Blacks and 490 Whites killed by police. All but about 30 of those killings were justified. There were 2,925 Blacks and 3,315 Whites murdered by criminals that same year. The statistics thus show the percentage of Blacks killed by police relative to the number of Blacks killed by criminals is less than, not greater than, the percentage of Whites killed by police relative to the number of Whites killed by criminals. https://ucr.fbi.gov/crime-in-the-u.s/2018/crime-in-the-u.s.-2018/tables/expanded-homicide-data-table-6.xls
