Two interesting articles that need to be read together. First, Germany tightens Swiss border controls: Swiss minister which reports that "Germany has tightened border controls with southern neighbor Switzerland to choke off a flow of illegal immigrants."
That's probably a smart thing to do, although the barn door was left open too long. That brings up the second article: Germany to tell people to stockpile food and water in case of attacks: FAS. If effect, the German government might not be able to secure your community if all those immigrants we let in go on a rampage. So hunker down and eat your sauerkraut.
Better advice might be to stockpile ammo. Unfortunately, the populace is largely unarmed. Unorganized and unarmed civilians beset by hostile mobs -- sounds absolutely medieval. But see Indiana Jones vs. the swordsman for an example of how that could play out with a satisfactory conclusion.
