Can vs Should

One of the life lessons that pretty much everybody learns, sooner or later, is that there is a difference between what you can do and what you should do. In the words of the illustrious Dr. Malcolm, "You were so busy thinking about whether you could that you didn’t stop to think about whether or not you should.” In the time of COVID, the Constitution has become a focal point for debates and argument which have now spilled over into other areas of civil action and protest. But the question remains about whether or not things that are permissible are in fact, beneficial? The President, tweeting fiercely, announces that he wants something done. In this case, he is threatening to deploy the military to stop the riots. Can he do that? Well… the answer is yes, he can. Should he do that? That is an answer that is not quite as clear, is it?
