OK I did some searching and found I'm no expert and I didn't understand the numbers: I think I put the 100K+ "unaccompanied children" at border each year together with the FBI raid cadence and thought it was all trafficking. Quick searching indicates: there's maybe 85K "lost contact" children after placement from border, which also doesn't mean what I thought; and FBI/LE recovered maybe 1000s of trafficked children in last decade. Still unimaginably large but not the numbers I thought I'd heard.
