The rate and severity of shootings are accelerating.

"The deadliest mass shooting in modern U.S. history came in October, when a gunman pent up in a Las Vegas hotel tower showered gunfire on concertgoers across the street, leaving 59 people dead and more than 500 others injured. A month later, a man opened fire on churchgoers in Sutherland Springs, Texas, killing 26. There were dozens of smaller-scale events this year. The Gun Violence Archive reports more than 14,000 people were killed and over 29,000 were injured in mass shootings in 2017. That might make it the worst year on record."
