Oddly enough, Obama probably hopes against hope that someday the US courts will allow the government to take children away from their parents because the parents are, say, politically conservative.
I doubt he needs "to hope against hope" for such power: the Department of Fatherland Security could easily cook up a list of "known terrorist organizations," start rounding up and redistributing children, and count on a tame Democratic [sic] party judge to call it legal. He'd probably rather disarm the workers and peasants, but I'm sure if he wanted to take children away from patriotic parents, he could make it happen this week.
At this point, it would still be too much, too fast, so they are far more likely to use a gradualism approach at first, and try to “blend it in” with media cover.
That is, pick selected targets, home invade to take their kids, arrest them on a contrived charge based on anything in their home, like expired prescription drugs, an “arsenal” of a handgun, a rifle, and a BB rifle, go through their library for any “incriminating style”, “right wing extremist” books like the Bible and a book by Ann Coulter; root through their garage to find anything that could theoretically be used in a bomb, like wire, electrical tape, a cellphone, gasoline, etc., all called “bomb making materials” in the arrest report.
As was the case of the engineer arrested in Louisiana, once the children are taken away, have a judge immediately give custody to ready “foster parents”, guaranteeing many months before even the possibility of their return. Have the parents in jail awaiting trial for a year and a half; then offer them another five years of legal battles to get their kids back.
They probably figure they can ‘turn’ children in a decade or less of total control, while ruining and impoverishing their family, hopefully driving them to destitution, crime, and most certainly welfare. If they commit suicide, great.
