My sister in law is mentally unstable, and has been in and out of institutions for a long time. Last night she decided to randomly PUNCH MY WIFE IN THE MOUTH in the middle of a restaraunt, in front of my daughter. She's 17 or 18 and her spineless parents said NOTHING at all to her. This is not the first time this has happened. I am in Afghanistan, so I am limited in what I can do. I want to file a restraining order on the bitch or something. I refuse to let my wife and daughter to be exposed to that garbage. I sure wish my wife had pressed charges on the spot, but she didn't. What options do I have?
