The correlation to jim crowe and red lining is exceptionally clear in regards to criminal behaviour of individuals whose families were impacted by those laws, that's not in question, how much of an impact it has is definitely in question. i.e. do they commit to these behaviours because of a society that pushed them to do this, or are they using the excuse of an unfortunate past to commit these behaviours? Are individuals in power actually using racist agenda to dictate policy or are they following empirical facts. I would hazard that the latter is emphatically not the case. I do believe many lawmakers use empirical data, but in regards to criminality and racial tension, I'm of the opinion that most lawmakers just throw their personal views and opinions behind their actions as opposed to the research and evidence therein (here, plainly, we see the negative impact that the liar has had because now EVERY research paper is questioned because the vast majority use 1 or more of his papers as referential material.

For the same reason people of jewish heritage claiming the holocaust negatively impacts them when they're 2-3 generations removed, sure it impacts them in how they were raised by their parents and how their parents were raised by their parents, but beyond that? Extremely doubtful that the event that changed the world only impacts the jewish community, especially when the concentration camps killed scores of people from every background with emphasis on minorities, the mentally disabled and the queer community.

I am not saying to disregard the research as a whole, I'm saying we need to repeat all of the research to verify the findings are accurate and reliable as opposed to just going 'well I see one bad thing and another bad thing and although they're clearly correlated, I'm arbitrarily going to note they're causally related'.
