“…Scholars agree that solitary confinement, in both the criminal and immigration context, has increased in tandem with mass incarceration (Patler et al, 2019;Reiter, 2016a;Rubin and Reiter, 2018;Sakoda and Simes, 2020;Schwellenback et al, 2019;Woodman et al, 2019). Legal and social science analyses alike demonstrate that solitary confinement, at least in the criminal context, is often imposed arbitrarily, by prison officials in perfunctory administrative hearings (Dolovich, 2012;Reiter, 2016a;Reiter and Coutin, 2017;Resnik, 2020), with disparate use among racial minorities (Pyrooz and Mitchell, 2019;Reiter, 2012Reiter, , 2016bSakoda and Simes, 2020), and those with pre-existing or new physical and mental health problems (Haney, 2018;Kaba et al, 2014;Kupers, 2017;Lovell, 2008;Patler et al, 2019;Reiter and Blair, 2015;Reiter et al, 2020;Williams et al, 2019).…”
