Tom Mauser lost his son in the 1999 Columbine school massacre in Colorado. Now, every time he looks up at the news and sees another school shooting he says he thinks the same thing to himself: “Have we not learned any lessons? Why are we not doing something to reduce this terrible gun violence?”
Mauser’s home state of Colorado has just passed new gun reforms and he says he’s “proud” of that legislation, but says he will keep on campaigning for changes to gun laws at the national level in the United States.
In the video above you can see Christiane Amanpour’s full interview with Mauser on how the killing of his son propels him to keep on pushing for reform.
