Supporters of SB957 argue that the bill is a crucial step toward ensuring the humane treatment of detainees in private civil detention facilities. They believe that the mandated oversight plan will help address existing issues related to health and safety standards, thereby improving conditions for vulnerable immigrant populations.

Critics of SB957 contend that the bill may impose additional bureaucratic burdens without effectively addressing the root causes of problems in detention facilities. They express concerns that the focus on reporting and oversight could divert resources from more direct interventions needed to improve detainee welfare.
