Jamaica: 70 killed in street fighting in May 2010. Nigeria: an estimated 1,000 people killed in the country’s oil region in 2008. Kenya: 140 lives lost in post-election riots in 2007. Mexico: 28,000 people dead from drug-related violence since 2006. Troubling as such figures are, they are but a small part of a much larger picture: there are up to 490,000 deaths annually that result from homicidal and non-conflict violence – a quarter of a million more than those who die in war zones.
