Thirteen years after the Columbine High shootings, Tom Mauser continues to be baffled by the proliferation of guns and gun violence in the United States.
The U.S. by far has the most gun violence among the world’s 23 wealthiest countries, Mauser said.
“We have the weakest gun laws and the highest gun-death rate. We are unique in allowing military assault weapons, as well as open and concealed carry. Other nations think we are crazy,” Mauser said.
