Homicide rates and game sales

I took a quick look at game sales and homicide rates.

Homicide (per 100 000 people) vs game sales (dollars per people) at 2011
Homicide (per 100 000 people) vs game sales (dollars per people) at 2011

Regression analysis was made using R (version 3.1.1) and lm. 2011 was year where I had null data points minimised.

Coefficients:
               Estimate Std. Error t value Pr(>|t|)  
(Intercept)      5.1644     1.8820   2.744   0.0158 *
adj.game.sales  -0.3391     0.2475  -1.370   0.1922  
---
Signif. codes:  0 '***' 0.001 '**' 0.01 '*' 0.05 '.' 0.1 ' ' 1

Residual standard error: 5.507 on 14 degrees of freedom
Multiple R-squared:  0.1183,	Adjusted R-squared:  0.05527 
F-statistic: 1.878 on 1 and 14 DF,  p-value: 0.1922

I assumed that violent homicides are linearly distributed.

While regression shows downward trend, the analysis does not suggest significant connection between game sale and homicide rates.
