Of the 200 million guns in the US just 0.005% were used for homicides in 2000. Actually, that assumes that each of the 10,801 homicides were committed with different guns, so the figure is likely to be less.
Wow! And this is a case for gun control? What percentage of the England football fans currently in Germany will be involved with violence? What percentage of people in a bar on Saturday night were involved in violence? If it is more than 0.005%, would that justify banning football and alcohol?
