Mass Shootings and Assault Weapons
UPDATE: This post has been updated to include the El Paso, TX and Dayton, OH shootings that occurred over the 24-hour period on August 3rd and 4th, 2019.
In his book “Rampage Nation” Louis Klarevas of the University of Massachusetts at Boston notes that gun massacres (defined as a shooting incident in which six or more people are shot and killed) fell 37 percent during the period the federal assault weapons ban was in place between 1994 and 2004, and that in the ten years after it lapsed, they went up an alarming 183 percent.
See for yourself:
Below are the deadliest mass shootings in modern US History. Note that only two (Columbine and Atlanta, both in 1999) occurred during the 10 year period (1994 - 2004) the assault weapons ban was in place.
Shootings where a semi-automatic rifle was used are highlighted.
