America has seen 74 school shootings in the last two years alone.
The attack with what police said was a semi-automatic weapon — "Shooter dressed in all black w AR-15 and vest and helmet. Cornered in bathroom by officers," according to Good Day Oregon's Kate Cagle — was the 74th since December 2012, when Adam Lanza killed 20 children and six adults at Sandy Hook Elementary School in Newtown, Connecticut. That's one about every eight days.
In 2014 so far, there have been 37 school shootings. As of February, about half of the incidents were fatal. Georgia tops the dishonorable list, with ten shootings reported since Newtown, while Florida is next with seven. Overall, 31 states are represented on the list.
