"It is not a good time to be a police officer in Sao Paulo, Brazil's largest city. So far this year, 95 officers have been murdered in and around the giant, sprawling city, according to official figures - up from 47 in 2011. The spike in fatal attacks has been blamed on a powerful criminal gang known as the Primeiro Comando da Capital (PCC), or First Command of the Capital." (Quoted from the article)
