The conditions in Arpaio’s prisons continue to get worse and worse, and readers may be shocked to learn that this kind of cruelty is both legal and accepted in the U.S. Indeed, even the prison psychologist recognizes that Arpaio’s tactics are counterproductive: addiction is a response to deep psychological pain, and inflicting
more pain on people does nothing to keep them away from drugs. Thus, Hari’s research again suggests that the U.S. government’s drug policy is deliberately callous and sadistic: it chooses to ignore the medical evidence about addiction and inflict needless violence on vulnerable people instead.
