imagine 11 million people being removed by police from their homes, all over the USA>
They're all shipped over the border to massive, unpoliced "border towns" right on the other side of this massive wall. no police, no electricity, no running water. Just people raping and killing each other, resorting to cannibalism and tweeting it. These "wall cities" would be the closest thing to the Walking Dead lawlessness that we'd ever see in our lifetimes. Families arriving with a change of clothes and a "good luck!" and being ejected into the desert.
Imagine the massive global coverage of it. imagine all of the possible side effects. Disease, whore houses, crime. imagine people just plain blowing up/burning the wall, or building a 31-foot ladder to defeat a 30 foot wall. No water, no utilities... nobody to even bury the dead.
11 million people require a LOT of resources that won't be there. Imagine when all that boils over.
I don't think many Trump "wall supporters" have thought about the look, the smell, the violence... 11 million Americans ejected into the desert to die, basically. I bet a few of them would rather shoot it out on US soil than go to one of those hell cities. One hole in that wall, and millions of starving, desperate people flood into american cities. Border patrol firing on starving americans trying to get back in. Imagine the mess it'd be.
Will never happen. And you probably know it too.
