Re [1], he explicitly says the opposite in the posts I linked to. You're just ignoring what he literally says and writes, and substituting your own feelings on the matter.
Regarding prisons, again, he is explicitly talking about closing down prisons. He has moderated his rhetoric more recently on this issue, but no, your interpretation of the subject is not what he's saying here, and it clearly isn't what he means, even today.
He has a long history on these topics. I'm not misinterpreting his comments.
