Do you have a source for “ privileged whites are given much lighter sentences or let off...for the same things in which blacks are prosecuted & incarcerated?”
Your link to the Innocence Project does not prove your point since your point was how many of each race are “let off”(not charged or simply not arrested but GUILTY of what?) or are “given lighter sentences (again, how many of each race get what sentence for exactly the same crime, in the same jurisdiction and have exactly the same criminal record/rapshee?)
Arrest, Charging with an Offense & Sentencing all occur prior to the Innocence Project ever reviewing the case.
