Yep, turning children against their parents, parents against their children, siblings against siblings, strangers against strangers...it's a-well known and effective technique of all totalitarian, repressive governments.  They count on the brainwashing and stupidity of its citizens to police society and turn against each other.  It wasn't only Germany who played that card, the Communists did it too and they did it well.  The US has been playing it since Sept. 11, 2001, at all airports near you when they tell to "inform the heroes at the Department of Homeland Scrutiny of any suspicious activities, persons or luggage" or with the billboards telling the sheep to do the same and with their 'orange alerts' - the message is a bit different, the objective is the same. 

And that is only the test-run, it actually gets worse after that.
