The interactive Homicide Monitor allows you to click on a country and see its murder count in a specific recent year, and the rate the number represents per 100,000 people. For some countries, you can also see the weapon most commonly used.
1 in 5 people were either Brazilian, Columbian, or Venezuelan. In fact Latin America and the Caribbean seem downright scary overall. I suppose it comes as no surprise that in the developed Western counties the U.S.A. stands out with a high number (it's almost as if we just have things sitting around waiting to kill people)… Bosnia and Libya have lower rates?!
