As an American, I think the tolerance for violence in American society is astonishingly high. I think that our high urban crime rates and our documented problems with police brutality are symptoms of the same disease. Certainly widespread gun ownership and latent racism are confounding factors, but I don't necessarily believe they're the driving force because they are a poor explanation for the violence we see in places like Baltimore and Chicago. I've come to believe that there is something very wrong with our attitude towards violence, and yet it's not clear to me why we are different or how we got here, let alone what policy changes could address it.
