It's not a matter of legal or not, it's a matter of honour. If we want to regrow to be even bigger and better than we have to do it right!
If we want to claim our History we have to accept our responsibilities.
And it's not a matter of "Look at what they've done to us", we have no control over what others do, but we do have a (small) say in what Rangers does to others. Let the others cheat, let the others bully and be bigots. But let Rangers be above that and reclaim the moral high ground.
