OK..... the proggies are going to surround NRA headquarters in northern Virginia, are they?
I’ve been there (fabulous gun museum). The building & grounds are designed to canalize protesters. The place is alive with surveil cameras. Demonstrations and/or violent outbursts will be well recorded & could increase membership.
BTW, disabled vets get life membership at half cost. I did.
I'm not sure where the protesters will gather. Access is via a very busy and fast but narrow road without shoulders (Waples Mill Road). There is no "greensward" on the NRA's side of the street. The parking lots are offset from the building in such a way that anyone congregating there in addition to breaking the law will not be in front of the building or visible from the road. Furthermore, there is no way to "surround" the building or march around it. It abuts impassible terrain on 3 sides. You could march "through" it and end up in the parking garage, I suppose. But no one could see you there and you would be tresspassing.
It is a very cleverly designed structure.
