Since when do average Americans (my white neighbors) form into mobs and attack businesses. Probably the closest thing we have done resembling that was lock up Japanese Americans in camps, and even that was pretty tame compared to what you are predicting. In any case, if that did happen it would not be a Federal issue and the National Guard would be called out by the State’s governer has has been done very time there is a riot such as the one you describe. The Fed has no jurisdiction in states unless it is to enforce the constitution, which was the case when Eisenhower sent the 101st Airborne to Little Rock, Ark. Even that was quite controversial.
