Because I believe the parameters should be expanded. And that is not for judges to decide. It it through democracy and parties elected that community standards are put in place. And nothing is absolute and settled.Point is there are ALREADY mechanisms in place to prevent their release. So why not allow the Judges and experts to make the decision.
While I don't like USA style three strikes and your out style legislation, I think the definitions of habitual and societally dangerous criminal behavior should be expanded. And it's pretty easy to start with multiple murders. After that repeated usage of firearms/weapons in the commission of crimes.
Expanding the guidelines for judges to use to protect law abiding citizens is a good thing.
