.....we should just focus on deporting those who have committed crimes other than illegally crossing the border or overstaying their Visas.
Isn't that the existing policy?
The Obama policy was
(1) to catch people at the borders, and
(2) deport criminal aliens.
The first can deal with some humanitarian issues -- like people dying of cold, heatstroke, dehydration, hunger, and snake bites.
The second involves betrayal of standards expected of us all.
So -- do not break up families; family cohesion is both a conservative and humanistic virtue worthy of honor.
