Whose fault is that? Donald Trump didn't illegally smuggle them across the border, their parents did. They have to be held somewhere while their parents, who knowingly broke the law of the land, are being prosecuted. Under no circumstances should they be treated as a "get out of jail free card", the moment you give people an inch, they'll take a mile. It's their parents, or other guardians, who put them through the hell of illegally crossing the border, across dangerous terrain and at the mercy of the cartels, Trump had nothing to do with that. On our end all we can do is ensure that their stay is as humane and comfortable as possible, but that costs money, and certain political parties outright refuse to adequately fund border security, so you should probably complain to them if you want to see real change.
