It is pretty clear that most of those released went right back to their madness, so release need not be an option at all unless an extraordinary personal change does take place and the person is accepted elsewhere beside his originating environment. Exceptions are accepted as possible but also as unlikely. Better yet insist a third party puts up a substantial bond.
The concept may need to be extended to similar individuals lacking specific political cover.
