“You shouldn’t run out in front of cars on the interstate or the highway and attempt to illegally protest. If you do, it should be at your risk, not at the risk of the liability of those individuals driving down the road.”

Speaking as a liberal, I AGREE! Stop blocking the damn interstate. Having said that, I see no reason for a new law. It should already be the fault of the people blocking the roadway if they get hit accidentally. And as the story above indicates, a law specifically addressing would be interpreted by some as a license to kill by some.
