It's basically the story of the loophole of "don't put children in jail and don't separate them from their parents either" at the US border. All good intentions, the consequences of which is that the number of illegal migrants coming with children has blown up, with children being used as a get out of jail card to enter the country illegally.
I am all for making exceptions in case of exceptional contributions. But you can't create rules without looking at the consequences of the incentives you create.
