@sean-king the only variable that can explain the high rate of mass shootings in America is its astronomical number of guns, Americans make up about 4.4 percent of the global population but own 42 percent of the world’s guns.
from 1966 to 2012, 31 percent of the gunmen in mass shootings worldwide were American, according to a 2015 study by Adam Lankford, a professor at the University of Alabama.America’s gun homicide rate was 33 per million people in 2009, far exceeding the average among developed countries. In Canada and Britain, it was 5 per million and 0.7 per million, respectively, which also corresponds with differences in gun ownership.
