Many years ago we passed an amendment outlawing the possession, consumption,etc,etc of alcoholic beverages. That worked out very well. Maybe we should try it with handguns.
My point was that if the foreign students are staying home because of their fear of guns in America, then if the illegals had the same fear, they too would stay home.
When the flag of a foreign nation is displayed in the United States, it must be flown below the U S flag. Since I didn't see a U. S. flag being displayed above the Mexican flag, the display was illegal. The student was just correcting an illegal act.
