What does it say about the humanitarian condition of US prisons and jails when one of the United States' closest allies refuses to extradite a person for fear that American prison conditions would drive him to suicide? This is exactly what happened ... when a British court ruled against the United States' extradition request for Wikileaks founder Julian Assange due to concerns that his health and safety cannot be assured in US custody. The United States fought vigorously to extradite Assange so that he can stand trial for alleged violations of the US Espionage Act, as well as other alleged cyber crimes. Judge Baraitser denied extradition due to the significant risk that Assange would be placed in solitary confinement, which she concluded would likely lead to his death by suicide. Assange has a long and documented history of mental illness. Prolonged solitary confinement " defined as the practice of confining people for 22 to 24 hours per day without meaningful human contact for a period of more than 15 days " can amount to torture, according to the United Nations. According to the Prison Policy Initiative, an estimated 37% of people incarcerated in US state and federal prisons have a diagnosed mental illness, as do an estimated 44% of incarcerated people in local jails. And studies have shown that approximately half of all suicides and incidents of self-harm in American prisons and jails occur among people held in solitary confinement.
