I like to cherry pick data too.
USA is the developed country with more Gunshot deaths per capita http://en.m.wikipedia.org/wiki/List_of_countries_by_firearm-...
UK 7 consecutive years with murder rate falls after stronger gun control, UK have more in common with USA than Jamaica or Ireland

The percentage of the crimes committed with firearms in USA is way higer than the half of Colombia, a third world country with multiple armed guerrillas for more than 40 years.
