More people died and were injured from January 6th 2021 than were injured and died at Fort Sumter which began the Civil War

 "More people died, and many more were injured as a result of January 6th 2021 attack on the Capitol than died or suffered injuries as a result of the attack on Fort Sumter."

(note: the Attack on Fort Sumter began the Civil War).

This is from William Bard and Michael Stokes Paulson from their book, "The Sweep and Force of Section 30"
