Many of these countries have similar problems with crime, drugs, urban deprivation and youth violence, others are more peaceful, but there is one simple thing that countries with less gun violence have in common with each other: they have fewer guns.
No one can predict the future of a more gun-constrained America with certainty, but the evidence from dozens of comparable societies points to a clear causal relationship between access to firearms and how often they are used.
