Apparently the Obama administration considers a family of evangelical Germans, who are in our country legally by court order, more of a threat to national security than the thousands of illegal immigrants it just released, according to this article at Human Events.
The administration has shown two things:
1) They don't like homeschooling in general because it irritates a key constituency, teachers' unions.
2) They really don't want to offend Germany right now, given that country's recent demand for the return of 300 tons of its gold reserves now "held" by the Federal Reserve.
Those little Scare Quotes are in order, I think, since the Fed also recently refused Germany's request for an audit of those reserves.
On the other hand, maybe I'm ignoring the natural reaction that Homeland Security personnel would have when confronted with such a scary-looking group of people.
