Six months after the mass murder of young students at Robb Elementary School in Uvalde, Texas, shootings at U.S. schools appear to have reached a five-year high, according to Education Week. The nonprofit magazine reports that 34 people have been killed and 88 have been injured as a result of 40 shootings at schools this year.
But James Alan Fox, a Northeastern professor who maintains the longest-running and most extensive data source on mass killings, says that many of those events do not meet the traditional criteria.
