Which of the following actions is NOT permissible regarding the treatment of detainees?

Withholding food and water as a form of punishment is a violation of ethical guidelines and human rights standards regarding the treatment of detainees. International laws, such as the Geneva Conventions and various human rights treaties, outline the obligations of authorities to ensure humane treatment and care for all individuals in their custody, which includes providing sufficient sustenance and hydration. Such punitive measures can lead to severe physical and psychological harm, go against medical ethics, and may even amount to torture or inhumane treatment.

In contrast, providing necessary medical treatment, allowing communication with family, and ensuring safety and security during transfers are all actions that support the well-being and rights of detainees. These actions align with ethical mandates to care for individuals in detention and uphold their basic dignity and humanity, reinforcing the importance of compliance with both legal and ethical standards in detainee operations.
