There will always be "dreamers". They will always have the same argument they have now: laws were broken but they weren't the ones who broke them, they haven't broken any laws, this feels like their home country, they don't know the language of what should be their home country, blah, blah, blah.
So, do we what to set as precedent? If we give this group amnesty, how do we not give the next one amnesty on the same grounds, and how much larger will it be after we send out a message to the world that you can sneak your kids in and we'll overlook our laws?
No deal. Not for anything.
