It strikes me as horrific that people of color, especially black POC, live with the real-life threat of being detained and deprived of freedom of movement. I read Ta-Nehisi Coates book 'Between the World and Me' a couple of years ago, and (again) had the privilege of forgetting about dangers I don't face as a white person, that black people of color face often daily: being incarcerated for minor offenses, of always having to be 'on guard' when talking with police (and any "wrong" move possibly leading to my death), of having police used as an intervention between me and a white person. Prisons, and the increased privatization of prisons in the last 10 years, exacerbate the problem of criminalization by incentivizing long detentions and overwhelmingly affect people of color...this strikes me not only as a legacy of slavery, but mimicking slavery in a fairly blatant way.
In my trainings in grad school, I worked in county jails and the California state hospital system (a specific system designed to separate and detain people who commit crimes but who also suffer from mental illness). It struck me at the time (and now with reflection) how little recourse people who are detained have in securing their freedom of movement even if they "do everything right." While over-incarceration and detention is a problem in general in the U.S., it's also a system that reinforces white supremacy and racism.
