American Exceptionalism is not relevant here.
A Wall to keep out dangerous foreigners would have protected that young girl and many other victims.
This is the Truth that all your games and evasions are designed to avoid.
We going to dun build us a wall Cleetus!
People can climb over walls, tunnel under walls, or just walk through the door of a wall with valid papers and overstay their welcome.
We just need to start crucifying (metaphorically, in the law courts) employers who hire Illegal Aliens...
And property owners who rent or sell to Illegal Aliens...
And automobile dealers and rental agencies who rent or sell to Illegal Aliens...
And currency exchanges who let Illegal Aliens wire money home...
And banks who maintain bank accounts for Illegal Aliens...
And school boards who provide educational services to Illegal Aliens...
And doctors and hospitals who provide any medical services to Illegal Aliens except for emergency lifesaving or life-sustaining measures...
And agencies that provide any form of monetary or in-mind welfare to Illegal Aliens...
And anyone who offers Sanctuary to Illegal Aliens...
Oh, and re-interpret the 14th, so that there are no more Anchor Babies recognized as birthright citizens after such-and-so a date...
Of course, scooping-up Illegal Aliens and packing their nasty asses back across the border, quickly and without appeal, once they're identified as such, will prove great fun, too.

Why?
Our country, our rules, and we can make up the rules to do and say whatever-the-hell we like.
A 5-4 SCOTUS ought to help with that.
Our country... not the Illegals'.
