Trump promised to deport all the undocumented migrants. All of them. That's roughly 10 million people.

How would you, within 4 years (he is famously a man of his word and we can count on him to accomplish his campaign promises within his presidency), find and then move 10 million people, and to where would you move them?

What does it look like to move 10 million people against their will? What mechanisms would allow for this?

I have an idea, but I'm curious your alternatives:

First, to find them, you could create a federal bounty program. Rat out illegals, get 100$ a head. Well, that might lead to rampant suspicion and neighborly misbehavior... somewhat exploitable too since you can get ICE to kick your annoying neighbor's door down by claiming they're harboring an illegal... not ideal. Maybe instead give NSA blanket wiretapping access to root them all out? Well, now they're listening to everything everyone says, but hey, anything in the name of freedom!

Regardless, awesome, now we've got ICE kicking down doors and dragging screaming families into the street. Part 1 accomplished. They load them into paddywagons and take them to local jails. Oops, those filled up within the first five days of the program. Now what? Stadiums? We're using those. Walmart parking lots with UNICEF tents? Sure, but what's to stop them from simply running away? Fences. We need lots of fences, and lots of UNICEF tents. Cut in some latrines (jobs!), run some plumbing, done. We've got some great staging areas.

Obviously, we should centralize these, right? We don't want to just take over every walmart parking lot in the country. Instead, while we negotiate with mexico and some other countries about how we're going to dump 10 million people over the border, we'll park them in several centralized locations, preferably out in the middle of nowhere because nobody wants a concentra--- sorry, undocumented migrant staging area, in the middle of their town!

That's a lot of people to move, 10 million. A greyhound bus fits, what, 30 people? 50? That's too many busses. We need trains. We can build the undocumented migrant staging area in remote areas with train access, just add an offramp straight into the camp- sorry, undocumented migrant staging area. Fix up some cattle cars, jam the people in there, gorgeous!

Oops, mexico told us to fuck off and won't take these migrants, now what? We can't just let them loose after having stuffed them up in there for a couple months, can we? I guess we can just keep them in there a bit longer while we try to negotiate with a couple other countries...

This sounds like the good version of America, right? With the screaming families being dragged onto mass transit and shoved into unicef tents? The alternative (aka, status quo for decades) is just lawlessness.
