In the 18 years since Zed Nelson’s seminal photography book Gun Nation was published, 500,000 Americans have been killed by firearms in the US. Half a million people dead and many more injured, Nelson returns to the people he met, re-photographs them, and asks why America is a nation still with an insatiable appetite for firearms.
Gun Nation explores the paradox of why America's most potent symbol of freedom is also one of its greatest killers.
