For me at least it is not a question of whether we need super max prisons or not. The answer is obvious of course we do with all of the violent inmates and criminals that we have and in a lot of cases inmates that are so violent and lack conscience so much that they can’t control their violent behavior. And even enjoy hurting people so of course we need institutions to deal with these people.
The question at least for me is how should we deal with these inmates. The status-quo would be do what we are doing as a country in most cases. Which is to warehouse them and hope they do not get worst and that these institutions the staff can deal with these people, or try to improve their behavior or give them an out from their destructive behavior. Incentive for them to improve their lives in prison in the time that they do.
