The American Thinker discusses the issue here, but it's not necessary to read the article in order to discuss the question. Here's the scenario. You're minding your own business, trying to drive from one place to another. Suddenly, you are confronted by people blocking the road. From the news, you are aware that people have been dragged out of their cars and severely beaten at these roadblocks. Increasingly, anarchists are armed. and people have been shot at these roadblocks. Frequently, cars are thrashed. What do you do? Do you stop in the hope that you will be merely inconvenienced? Do you drive on even if it means running someone over? Would your decision change if you could see that the anarchists are carrying weapons? Would you then be more likely to stop or less likely to stop?
