Here are some of the graphs to give you a hint of the content:
Homicide has a slight negative correlation with gun ownership. But this graph doesn’t tell the complete story because it doesn’t include the murder of citizens by their governments. Nearly 100 million people were murdered by their own governments in the 20th Century. All the major genocides were enabled by strict gun control. These numbers are not included in the above graph and if included they would give the above graph a huge negative correlation.
As gun ownership goes up the corruption goes down. I find this one of the most interesting graphs. I wonder about the causation. Do corrupt government restrict gun ownership out of fear or is corruption lower because people own guns? Both? Neither?
