Non-governmental organization Human Rights Watch (HRW) has criticized the use of solitary confinement in the United States, particularly in immigration detention centers.
HRW revealed that California Immigration and Customs Enforcement (ICE) detention facilities used solitary confinement for an average of 27 days, as per the data shown between 2018 and 2023. Earlier this month, detainees at California ICE facilities started a labor and hunger strike to protest their conditions, including the use of solitary confinement.
