I think you make the mistake of thinking that people oppose all state violence. Many people approve of some state violence in the name of maintaining societal order, but oppose torture. And I would posit that coercive incarceration is a form of torture.
It is a mistake to believe that people are ideologically consistent. And I would be hard pressed to believe that torture is not more extreme or less legitimate than other forms of violence.
