The only problem with the chart in Lord Tio's post is that all it says is that gun ownership went up and violent crime went down. There is still no causal relationship established between firearm ownership and crime..

It does not include such factors as increased or decreased enforcment of laws by law enforcment which also causes violent crime to decrease.

Probably other factors that caused crime to decrease as well.

Violent crime is increasing in some places while gun ownership is also going up. If I use the argument above now I could flip flop it and say that crime is increasing because of the increase in private firearm ownership.
