Of particular concern to some on the right is the term “systemic racism,” often wrongly interpreted as an accusation that everyone in the system is racist. In fact, systemic racism means almost the opposite. It means that we have systems and institutions that produce racially disparate outcomes, regardless of the intentions of the people who work within them. When you consider that much of the criminal justice system was built, honed and firmly established during the Jim Crow era — an era almost everyone, conservatives included, will concede rife with racism — this is pretty intuitive. The modern criminal justice system helped preserve racial order — it kept black people in their place. For much of the early 20th century, in some parts of the country, that was its primary function. That it might retain some of those proclivities today shouldn’t be all that surprising: https://www.washingtonpost.com/graphics/2020/opinions/systemic-racism-police-evidence-criminal-justice-system/
