Except that prison doesn&#x27;t rehabilitate at all: it does the opposite and makes people worse. The rehabilitative theory of justice is essentially nonexistent in the US, nobody even pretends. Instead it&#x27;s about punishment&#x2F;retribution and &quot;keeping them off the streets&quot; during the period of their sentence. The coma solves the second concern, but isn&#x27;t cruel enough to solve the first so I don&#x27;t think you&#x27;ll ever see it accepted in the US.
