Youtube: The Greeks are spraying pig's urine on Muslim refugees who are trying to cross the border into Greece from Turkey.
Now I understand that if you're a Mohammedan, you think that it's a horrible thing to do, but the Greeks are just trying to hold onto their sovereign nation and tall fences make for good neighbors. Not to say that Turkey is a good neighbor irrespective of how high you might build the wall.
The strategy is apparently working in the short term because the would be refugees don't like being sprayed with pig urine.
