Shootings that left four or more people wounded or dead occurred in the U.S. more than once a day this year, reports the New York Times. A total of 462 people have died and 1,314 have been wounded in such attacks this year, many of which occurred on streets or in public settings. It is impossible to know whether the number of such shootings has risen in recent years because databases go back only a couple of years. Experts debate whether mass shootings by the standard of four or more dead have remained level or ticked up slightly in recent years.
Two databases that track mass shootings — shootingtracker.com and gunviolencearchive.org — depend on news accounts and are not official. Nonetheless, they give an indication of the widespread nature of such episodes. Since January, there have been at least 354 such cases in about 220 cities in 47 states, says shootingtracker.com. Ted Alcorn of Everytown for Gun Safety, which advocates gun control, said the shootings with multiple victims were a tiny subset of everyday gun violence, which takes about 88 lives daily. Criminologist James Alan Fox of Northeastern University said the number of mass shootings has roughly held steady in recent decades.
