So what is so unreasonable about wanting a system where if someone commits a murder, and suffers from mental illness to be sentance to be in a mental facility for at least the minimum someone would spend in jail for the same crime, before he is given an oppourtunity to be released?
Because if they are cured of their mental illness then holding them serves no purpose other than vengeance. It, in effect, penalizes the person for becoming ill and as I've already said, enlightened societies don't do that.
And you never answered my previous question, if there is NO WAY he will be getting out soon, then why the oppourtunity?
There is a difference between what is possible and what is reasonably expected. While it is possible that he could be released tomorrow (and should be given that opportunity if he is cured) it is highly unlikely that he will be free any time soon.
