Putting a chilling effect on protesters playing in the middle of the road
There should be a chilling effect on demonstrating in the middle of a highway. It is a danger to the protestors and to the public. I do no think the 1st amendment protects someone lying down in the middle of the road. There are already cases that say one cannot shout fire in the middle of a crowded theater. You might say there is a chilling effect on shouting fire. But that does not mean you get to do it.
