Excellent article. Trump won’t have to load up trains and buses, but he will have to ensure enforcement of the laws and go hard after businesses, cities and states that violate federal law by harbouring and employing fugitives, and who pass state and municipal laws granting benefits to these lawbreakers.
Probably stating what all here know but...there are laws already on the books to prevent that. Businesses just started ignoring them.
I say enforce them and make all violations retro-active. Go over a business' records and track how many of those don't match up with INS/ICE records. There will be a big discrepancy. And the fines will leave a nasty burn mark.
