"Systematic Systemic Racism"

To a boy with a hammer, everything looks like a nail.

1. Individual racism:  Requires that he is aware, though not necessarily conscious, of a personal characteristic labeled as "race".  Less abstractly, a racist believes that there is a hierarchy of "value" among the races, where at the very, Whites are more "valuable" than Blacks.  More specifically, it would appear in applying the value, "do unto others as you would have others do unto you," Blacks are not considered "others" and therefore this principle does not apply to them.

2.  Can one have a formally neutral legal system whose outcomes are racist?
Yes.  The inputs matter.  Individuals with racist values can skew the results to produce racist outcomes ... garbage in, garbage out.

3.  Would it be possible to segregate the criminal justice system?
Blacks are arrested, tried, sentenced, incarcerated, paroled by Blacks; Whites by Whites, etc.  But what if the law enforcer and law breaker are not the same race?  Should law enforcement stand down, back off, and let the law breaker escape?  This would probably drive communities to greater segregation, and probably greater inequality and exploitation.

4.  You could learn how to get along.
