Peter Bergen wrote for CNN about the ongoing problem of gun violence in America:
Americans often think of themselves as belonging to an exceptional nation, and in many ways they do. They belong to a tolerant, multicultural society that has led the world toward a more innovative and more inclusive future through new technologies and a unique embrace of diverse cultures.
But the United States also leads the world in other ways that don't match the often complacent self-conception that many Americans have of their own country. The United States locks up more of its population proportionally than any other country in the world, including authoritarian regimes such as Russia and China, according to the International Centre for Prison Studies.
It also leads in another dubious statistic: More Americans are killed by fellow citizens armed with guns than in any other advanced country, according to the Small Arms Survey.
