The thought crossed my mind long before the "occupy wall street" campaign. To my recollection, there is a dog-walkers' park right infront of the main lobby at Brooklyn, and this would make a perfect venue for a prolonged rally, provided the dog walkers didn't mind our presence. I even thought how cool it would be for "active" and "inactive" publishers to picket alongside the Df'd and DA'd in a show of unity. Those active and inactive Witnesses could have their faces covered, perhaps bound with bandages, with a brief but powerful slogan on their t-shirt to tell the world what would happen if they were to show their faces.
I suspect the Society are already one step ahead of us on this, as I'm sure it's either been done or planned before. They probably have some sort of contingency plan that would swing into operation if it were to happen. That doesn't mean we shouldn't try it if it were legal. I know a lot of us would fly across to New York to be in attendance if it were organized (and legally viable).
