"Judges travel within the parameters that we set for them, via the legislature."
Most have not done that lately. Where have you been? Most judges lately have been making their own rules as they go along and the legislature be ......
Sure they have - those parameters are just not as narrow as legislators want you to believe. Congress and the state legislators have been abdicating their responsibilities to the courts for decades now, and they generally prefer it that way - they take the credit for the things that people like, and they get to blame the courts for whatever goes wrong. It's perfect. Well, perfect for spineless legislators, anyway, which is most of them.
