Your beloved Fox and Salinas managed to drive them out --- no problem. What goes north can go south. They sent them over in unventilated box cars and semi trailers --- often half dead. We can send them back in comfortable air-conditioned buses.
You may not believe this --- but some people actually are deported --- you can go stand at the bridges and see it --- not traumatic at all like you claim. The INS takes them over to the gate, opens it, and they walk back home --- where there are buses, taxis, hotels --- within minutes they're just blended back in with their fellow citizens. No one stands there crying when they're let out of the buses and vans --- not even the deportees cry.
