Reaching Critical Mass on Mass ShootingsIn just over a week, a spate of mass shootings devastated the USA: in Gilroy, CA, on July 28, 2019, three people were killed and 12 injured at a festival; in El Paso, TX, on Aug 3, 22 were killed and 24 injured at a shopping centre; and in downtown Dayton, OH, on Aug 4, another nine were killed and 27 were injured. It has left the country aghast, overwhelmed, and looking for answers to whether and how these killings can be prevented. Over 250 separate mass shootings have occurred in 2019.
