Given the same crime, should justice and sentencing be arbitrary or equivalent?
Contextualized to the Nixonian origins of the "war" on "drugs," the US socioeconomic sentencing disparities are the common element linking all drug convictions, from the streets of Baltimore/Camden/Detroit to any one of the Sacklers palatial manors.
If you take "just" to mean "justifiable", sure. That meaning doesn't really make sense in the context of this discussion though, so yes I am invoking one of the definitions related to fairness.
