What we need to do, in cases like this, is very simple. At night, a Jewish commando needs to go in there and bust up the entire place, like the Mafia does. In other words, THEY NEED TO BE DEATHLY AFRAID OF DOING *STUFF* LIKE THIS! If they get away with it, they do it. If they learn there are consequences, then they'll think twice.
Let's not every forget how Rabbi Kahane fought back with the JDL in Brooklyn. He fought back!
NEVER AGAIN!
