| What Happened? |
Only Hawaii, Vermont and North Dakota had no mass shootings (four or more deaths/injuries caused by a shooter with a firearm).
The other forty-seven states and the federal government administrations, as well as the congress and courts, are treating the effect instead of the cause (Are You Simply Treating Your Symptoms?).
The following HTML table covers the mass shootings state by state, in most populated state down to least populated state order:
