The pattern to this thread has been interesting. Some opinions were voiced on the morality of what is going on, and the response has basically been, "Nyah, nyah, Obama did it too!" Reminds of when people complain that Al Gore flies in pollution-producing airplanes, as if that's a valid argument for something.
To play devil's advocate, it would be interesting to conduct an experiment but unfortunately it can't be done. I'd like to see what would have happened if those kids were white Europeans.
But to take a step back, I am amazed at the first rate propaganda effort that was put into convincing the richest nation on earth that one of their biggest problems is illegal immigration. Middle class income has stagnated since Reagan, do you really think that is the fault of a few gardeners and farm workers. Your own corporations shipped your good jobs overseas and you allowed the financial sector to rape your economy to mostly enrich people who were already doing ok, and you think that your problems can be solved by spending untold amounts of money getting rid of illegal immigrants who are mostly working in jobs no one else wants? If you want to stop illegal immigration, well ok, I get that, but I can't help thinking this is mostly a diversion and those caged kids are just pawns in a marketing scheme.
But just for the record, if it can be shown that there was a concerted effort to specifically separate kids from their parents as an enforcement tactic, than that must come pretty close to being a crime against humanity. I don't know the legal specifics of what constitutes such a crime so I can't say. But it sure is convenient that the USA is not a signatory to the International Criminal Court.
