No, people typically get put into solitary confinement for their behavior after they are already in prison. Do you think that solitary confinement is part of a judge’s sentence? It is not.
So your comment and cite are irrelevant to the discussion. If you have an answer to my original question (What about all those who are in prison for non-violent crimes, including drug possession, do you have anything to say about them?) feel free to provide it.
