Actually, have studied a fair amount of 'case-law' and 'precedence'.  Immigration law, too.  Not so much since the likes of John Yu started referencing "precedents" articulated by Karl Schmidt.  Kinda lost my appetite for "legal" rationalization of state-sponsored crimes after that.  But suffice it to say I'm not a complete stranger to the inside of a law library.  Thus we're never gonna get around the impasse between your uncritical acceptance of the utter divorce between "moral" and "legal" in adversary law and my (albeit cautious) dissatisfaction with it.

I'm kind of like an old friend and mentor who returned to his Lord in '08.  Studied Shari'a at Alighar Muslim University to get a Shari'a practitioner (lawyer's) license in India, got his barrister's license in England, and passed the bar in the US.  Never practiced law because he hated lawyers.
