The document discusses the concept of 'oxygen torture' (o2t), a method of psychological and physical torture used in prisons, particularly in Switzerland and Guantanamo Bay, resulting in chronic oxygen deprivation and severe long-term harm to victims. It details the insidious nature of o2t, where prison conditions and techniques lead to irreversible brain damage and physical deterioration without visible signs, making it remarkably effective and undetectable. The author also alleges state-sanctioned murders and complicity of various institutions in this form of torture, pointing to a broader context of human rights abuses and ethical disregard.
