So, to clarify for both of you, human trafficking has long been a major priority for ICE and HSI in particular. It's not that it gets ignored, but rather that it's a constant fight and news generally isn't reported on it because it's so horrifically common as to be background noise, the fact that the victims tend to be minorities, and the fact that it's as much a problem inside the U.S. with Americans being trafficked.
Now, in fairness to Trump, his allowing ICE and CBP to do more actually did crack down on both the crossings AND getting kids away from the traffickers. But it wasn't done simply out of the goodness of his heart; it was really a bonus of his stepping up border enforcement.
Actually that's because of-
-it being under the UN. Ninja'd.
Anyway...yeah, sadly UN peacekeepers are reliably shit when it comes to human trafficking. Same crap went down in Bosnia during the Yugoslav Wars of the 1990s (look up Brcko's 'Arizona Market but do it on an empty stomach)...it was REALLY bad. The locals don't really care because they're usually on the take to look the other way.
The U.S. military, for all its faults, is at least VERY strict about human trafficking and comes down HARD on anyone involved. Problem is whether their ROE will allow it, especially in a foreign country.
As for the T visas...I do remember that being a thing but it's less a resistant bureaucracy as a slow one (take it from someone who works in one in the private sector -getting things moving, even under a direct order from the chief executive, is NOT a quick process. Because you need to have the process for issuing them, you need to coordinate with other teams/departments/agencies, you need to have the resources and the personnel to implement the change, and there needs to be effective communication.
It's not "the bureaucracy undermining Trump" in this case -especially in an issue where there is literally no reason to do so give the wide bipartisan support anti-human trafficking initiatives have among politicians and everyone else, but just the fact that the federal government takes forever to implement anything.
Also please excuse the weird grids. I'm on my phone and they appeared, and my attempts to remove them have failed.
