The last line in the video about mass incarceration I think put it very well that "we've chosen the response of deprivation of liberty for a historically aggrieved group whose liberty was never firmly established to begin with". Because POC, and predominately BIPOC, people have historically been stricken of liberty as compared to Whites, that pattern continues in all realms of our society, thus, "redlining" them to continue those patterns, one being mass incarceration, and often the "preschool to prison pipeline". This has obviously been continuing for years, stemming from the era of slavery. Mass incarceration is rightfully named modern-day slavery because that is what it is.
