I'll do my own thinking, as you suggest, since that's what I was taught to do in school and have done all my life.  As a third generation of a  military/law enforcement/government family  I've seen law at work in letter, spirit and the consequences when not followed. Certainly laws change for a variety of reasons, through process.    There could have been a mature discussion, but your last juvenile snipe remark put an end to any interest I have.
