According to this site: http://www.nationmaster.com/graph/cri_tot_cri-crime-total-crimes
the 2nd most violent nation in the world, NOT adjusted for population is - wait for it - the UK. Now, I usually don't trust the Uninformed Nation's studies and this one dates back to 2002. However, Mitchell has reported several more recent incidents of violent crime increase in the UK. Looks like you don't need a gun to kill or maim. Maybe the Brits' lack of testosterone makes them easy prey for thugs armed with nail clippers. Or, maybe they just like to be mugged.
