I'm with you, Ceejabee: "...there's no reason or logic that prevents our FN from doing the very same thing ..." But, you see, this has never been about reason or logic.  It's tradition, comfort, habit and fear.  All that stuff, aided and abetted by the governments of good intentions.  So: no mystery why there is no "will."  

Not a lot of "honesty", either, which may be the core reason why the Murdered and Missing Inquiry isn't going anywhere fast. Who in their right mind would "rat out" their abusive, murdering friends and relations?  But I digress...

You're perhaps evoking the Post WW II founding of Israel with you comment.  Zionism didn't persuade all Jewish people everywhere to "call the moving company".  If it ever comes to that regarding FN, not every band would do the same, either. The motivating factor in the late 1940s was the cohesion of religion.  FN bands don't have that, either.
